DeltaE* for Android
Version 4.6.0 b349 (2014-03-03)
You can see a patch reflection density as
defined in ISO 5-3 (Status A, Status E, Status I, Status T).
A third data display was added to the Info
window and you can, for example, see the CMYK, L*a*b* and Density values
of a patch at the same time. You can also hide two of the three data
displays if desired.
Get a screenshot (PNG format) of the Info
window simply by pressing “I” on the keyboard.
- You can now display the reflection density
of a measured patch as defined in ISO 5-3 for all chart types (Unconstrained
measurements, Custom chart, PatchTool file).
- As with Unconstrained measurements, you can
now see XYZ, L*a*b* or L*C*h* values of any measured patch for a Custom
chart or a chart defined by a PatchTool file.
When measuring a chart while using a PatchTool file as a reference, you can
compare L*a*b* and L*C*h* values between the reference file and the
measurements and get the CIELAB color difference (DeltaE*). You can also
compare CMYK from the reference with the measured density.
- Whenever available, display the data for any
mix of M0, M1, or M2 Measurement conditions.
- Added the Density data field in Patch-Reader
CGATS export dialog.
Export dialog: You can
now export Density values for any opened file which contains spectral data
(File types: CGATS, plain text).
tool: Improved patch navigation, selection and display when measuring
patches with the ‘Custom chart’ and ‘PatchTool file’ chart types.
- Fixed a bug where a measuring instrument would not
connect immediately when opening the Display-Check, Display-Reader or
Patch-Reader tool. The problem happened when ‘Eye-One Display’ or ‘i1Pro /
i1Pro 2 (non-XRGA)’ were the previously selected instruments.
- Fixed a bug where an OutOfBoundsException would sometimes
happen when switching from a ‘Custom chart’ to a ‘PatchTool’ file in
- Fixed a bug where a message referring to ‘DUAL scan’
would be shown in the Patch-Reader window when measuring patches on a strip
with the ‘i1Pro / i1Pro 2 (non-XRGA)’ instrument driver. Only the message
was wrong and it did not affect the measurements.
- Fixed a bug where an OutOfBoundsException would happen in
Display-Check when making measurements just after opening the ‘Instrument
info’ dialog. The problem was associated only to the following colorimeters:
DTP94, Eye-One Display, and i1Display Pro.
- (Mac) Fixed a bug where an IOException was raised when
saving a profile while importing patches from a TIFF image or extracting a
target from an image. The problem occurred if the profile was already in use
in another opened PatchTool file.
- (Mac) Fixed a bug in the ‘Extract Target from Image…’
tool where the target layout was not properly positioned when extracting
targets from images of the same size one after the other.
- (Mac) The file names are now properly defined when
exporting multiple files from the Patch-Reader export dialog.
- Contrary to prior notice, Version 4.6 still supports Mac
computers with PowerPC processors.

Version 4.5.0 b332 (2013-10-02)
Added options to export to the generic CxF Version-3 (CxF3) file format (*.cxf)
as well as to four CxF3-compliant file types dedicated to X-Rite’s
i1Profiler (i1Publish). See Application Note 10 (AN-10) in the
Tutorials page for more
Supported data fields: ID, Name, XYZ, xyY,
L*a*b*, L*C*h*, RGB, CMYK, and spectral data
Supported i1Profiler file types: Chart
Measurements (*.cmxf), Patch Sets (*.pxf), Test Charts (*.txf),
i1Profiler export limitation: i1Profiler
support is limited to RGB and CMYK data flows (i.e. CMYK+n and display
measurements are not supported). In addition, except for a small option
with *.cmxf files, there is no support for Custom Resources. Additional
features may be added in future versions as knowledge is gained and need
is expressed by user feedback.
- Color Management Module (CMM) changed from
LCMS 1.19 to LCMS 2.5. This change has an impact on all profile-based color
conversions. Here are a few of the consequences of this change:
- Full support of ICC v2 and ICC v4 profiles (LCMS
1.x had partial support of ICC v4 profiles).
- Important notice: Because LCMS 2.x was
almost completely re-written, you should not expect to obtain EXACTLY the
same numerical results as the ones obtained with LCMS 1.x, although the LCMS
author is confident that the newer version is more accurate.
Gamut Tools: Computed
gamut volumes may be different from those computed in previous versions.
Extract Target from Image
tool: Improved mask layout management.
The mask layout is scaled and positioned to
follow changes in the tool window size and in image scaling.
Maximum scaling has been increased to 3200%
to better see single-pixel-per-color targets.
You can now move the image and the mask at
the same time by pressing the ‘Alt’ key (on Windows; use the ‘Option’
key on Mac) while doing a mouse drag.
In a given session (i.e. until PatchTool is
closed), the tool window, the image, and the mask sizes and positions
will be recorded and used for the next image, if the image is of the
same dimensions. This is useful when extracting targets from many images
taken with the same setup.
The mask cannot be positioned outside of the
image; the mask will snap to the image edges.
Any embedded profile will now be copied as
is instead of being reconstructed from captured data.
Extract Profile from
Added these fields to the tool interface:
Creation software, Preferred CMM, Profile Copyright.
Any embedded profile will now be copied as
is instead of being reconstructed from captured data.
- Improved xy to CCT algorithm. The algorithm
is now more accurate over a larger chromaticity area. The acceptable
isotemperature zone is between 2000 K and 1 MK. A warning is issued when
calibrating an instrument with a white patch if Duv is not within plus or
minus 0,05 (Duv data is not provided).
Patch view tab: Added
entries for Horizontal and Vertical layouts of the IT8.7/4 and ECI2002
targets in the ‘Rows’ menu.
- Extract Target from Image and Extract Profile from File
tools: Fixed the bug where an embedded ICC v4 profile was saved as an ICC v2
- Patch view tab of opened files (standard files and
Compare files): Corrected a bug where the RGB values are properly replaced
when using the ‘Replace the patch color with…’ contextual command (Shift +
mouse Right-Click) and the file data was derived from imported RGB values.
- Patch view tab of Compare windows: Corrected a bug where
the CMYK values are properly replaced when using the ‘Replace the patch
color with…’ contextual command (Shift + mouse Right-Click) and the file
data was derived from imported CMYK values.
- Contrary to prior notice, Version 4.5 still supports Mac
computers with PowerPC processors.
Version 4.1.0 b321 (2013-06-03)
Display-Reader tool: Perform unconstrained
emission measurements on any display, even one not connected to the computer
on which the program is running.
This tool can be used with all
supported colorimeters and spectrocolorimeters.
Measurements can be done with or without a
Color Correction Matrix.
Measurements can be done with or without measuring the display White
Point (Note: The Eye-One Display 2 set for CRT and the Spyder2 require
calibration to be done on a white patch).
Obtain ABSOLUTE measurements: xyY, XYZ,
spectral data (for the i1Pro and i1Pro 2). If you measure the White
Point, you can also get L*a*b* data relative to this White Point.
When you measure the White Point,
you can also obtain PROCESSED data (xyY and XYZ, with Y normalized, and L*a*b*,
relative to many Standard Illuminants, in Absolute-Colorimetric or
Export ABSOLUTE measurements in a RAW file
that can be opened in a spreadsheet.
Export PROCESSED data in a CGATS compatible
file which can be opened in most programs that support this format. This
file can be opened in PatchTool and compared to other color lists.
A timer can be used to take measurements at
fixed time intervals.
Substrate Correction tool: Use this tool to
convert measurements taken on a backing material, a black substrate for
example, as if they were taken on another backing, a white substrate for
example, as described in
ISO 13655:2009, Annex A. You can also use it to
convert standard or custom colorimetric aims data sets, the aims of
12647-2 for example, when your substrate/paper is not within tolerance, as
- Let the program find the patch with MAX
Lightness (L*) in your reference data or assign any patch with its ID.
- Let the program find the patch with the MIN
L* in your reference data, assign any patch with its ID, or write-in the L*a*b* values.
- Specify the target data using either an
opened PatchTool file or write-in the L*a*b* values. If using an opened
file, let the program find the patch with MAX Lightness (L*) in your target
data or assign any patch with its ID. The CIELAB difference between the
reference and the target is shown as well as the individual L*, a*, and b*
- The tool can be used with files of any size
(i.e. number of patches).
File-to-File Transfer tool: Transfer any of the ID, Name, CMYK, and RGB data
fields between two files opened in PatchTool. This tool is particularly
useful to copy reference CMYK or RGB data into a measurement file when you
intend to generate a profile from this file.
- Will now detect when importing xyY or XYZ
data where Y is scaled between zero and one (0-1) instead of the more
traditional zero to one-hundred range (0-100). A dialog is presented to
- i1Display Pro: Added support for the new
‘Burst’ measurement mode dedicated to displays which have pulsing
characteristics, such as plasma screens. The EDR files were updated, with
additional files for RG-Phosphor, Plasma, and OLED displays.
- The items of the ‘Tools’ menu were reordered
and grouped in categories.
- Measuring instruments: Instrument detection
and connection is more robust.
- Fixed an issue in Patch-Reader when exporting
unconstrained measurements without selecting the patch name in the exported
file. In these circumstances, an additional data separator was introduced in
the data section. This extra separator had no consequence when the files
were opened in PatchTool.
- Removed redundant information text in the ‘Select
Compare’ and ‘Tweak Target’ windows.
- Fixed the issue where the PCS graphics were improperly
redrawn in the Gamut Tools.
- Contrary to prior notice, Version 4.1 still supports Mac
computers with PowerPC processors.
Version 4.0.0 b312 (2012-09-17)
- Added support for the X-Rite i1Pro 2
This instrument is used in the Display-Check
and Patch-Reader tools.
Supported models: i1Pro 2 M0/M1/M2, i1Pro 2 M2 only.
Supports the M0, M1, and M2 measurements mode for reflectance
Supports X-Rite’s XRGA calibration standard
for reflectance measurements.
Assign a Color Correction Matrix to the
The i1Pro 2 can be used in PatchTool on a
PowerPC Mac with the older i1Pro driver; in this configuration, the
i1Pro 2 behaves as an i1Pro. The new i1Pro 2 features are available only
in conjunction with the new i1Pro 2 driver, which requires an Intel Mac
with OS X 10.5.8+.
- i1Pro and i1Pro 2:
- Both the older i1Pro and the new i1Pro 2
drivers are provided. The i1Pro and i1Pro 2 instruments can be used with
either driver in Display-Check and Patch-Reader. The i1Pro2 driver is XRGA
compliant and the older driver is NOT XRGA compliant. The new driver is
referred to in PatchTool as ‘i1Pro / i1Pro 2 (XRGA)’; the older diver is
referred to as ‘i1Pro / i1Pro 2 (non-XRGA).’ You can thus make measurements
with your instruments with or without XRGA calibration.
- Calibration with the ‘i1Pro / i1Pro 2 (XRGA)’
driver always require that the instrument be positioned on its white
calibration tile, even for measurement modes other than reflectance.
- You can assign a different Color Correction
Matrix to each driver.
tool: Patch-Reader gives access to the i1Pro 2 features, with support for the
M0/M1/M2 measurement conditions and for its zebra ruler optical reader. Even
the older i1Pro benefits from the new i1Pro 2 driver, with the capability to
use the ’patch correlation’ mode with a PatchTool file.
CGATS export dialog: When saving
measurements from any Patch-Reader mode, you are now presented with a dialog
which enables you to select file options. These options include: a selection
of data fields, spectrum scales, spectrum ranges, and decimal separators. If
making measurements with multiple measurement conditions, the dialog also
offers options to save the data in one or more files.
Select any combination of M0/M1/M2 measurement conditions for each
measurement, and get up to three spectrums, one per measurement condition,
each time you push the i1Pro 2 button. You can thus see in one click the
susceptibility of a paper to fluorescence. If you did measurements in
multiple measurement conditions, you can export the measurements in a single
file, in a separate file for each measurement condition, or in separate
files plus a single file.
There are new options for strip measurements: an option to use or not the
i1Pro 2 ruler, and an option to set the instrument to better recognize low
resolution targets. These options’ availability depends on the instrument,
the selected driver, and the selected measurement conditions. In addition,
when measurements are made in reference to a PatchTool file, you can now
select to make measurements in a ‘patch correlation’ mode, without an i1Pro
2 ruler, where the file values are used to do a fast check on the validity
of the measured data and to detect the direction of the scan. If you did
measurements in multiple measurement conditions, you can select which data
you want to keep, in a separate file for each measurement condition.
When using the ‘i1Pro / i1Pro 2 (XRGA)’ driver with either the i1Pro or the
i1Pro 2, you can select an ‘Adaptive measurement’ mode for emission
measurements in the Instrument Info dialog. When selected, the measurement
time is longer for low luminance patches in order to provide more accurate
Extract Target from Image
tool: This tool, designed to directly extract the average of target patches
in full size photographic images, now supports 8 bit and 16 bit TIFF CMYK
- Open CxF Version-3 files, such as the ones
generated by the X-Rite i1Profiler program:
- Open generic *.cxf files as well as files
with content-specific data, such as *.axf, *.mxf, *.txf, etc.
- Import a collection of device-independent
data type measurements, plus RGB and CMYK, when available, into a PatchTool
file. The measurements collections must have the same number of patches to
be imported in the same file.
- Supported top level Resources: Object
Collection, Color Specification Collection.
- Supported device-independent data types:
Reflectance Spectrum, L*a*b*, L*C*h*, XYZ, xyY, AdobeRGB, sRGB.
- Supported device-dependent data types: RGB,
- Non-supported elements: Custom Resources,
Profile Collection, Tag Collection, and others.
- Compare window: Added DeltaCh (dCh), the
chromaticness difference, in the list of available deltas. These deltas are
used to compute individual differences between each pair of compared
patches, in the Tabular data tab, and for global statistics in the Stats
tab. The chromaticness, defined in DIN 55981, ISO 12646, and ISO/DIS
12747-8, is better used to evaluate color differences for near neutral
colors, typically with a Chroma (C*) of less than seven. dCh is referred to
with various symbols, such as dEc, dF*, or ds. The chromaticness difference
is now included in a saved Compare file whenever L*a*b* data is selected for
- Added xyY as a selection in the color space
- Added the ‘CIELAB / a*b*Ch’ menu item to the
DeltaE* menu. With this selection, you can easily get the chromaticness
difference (dCh) between any two patches of opened files.
- It is now possible to select, with a
contextual popup menu, either a linear scale or a logarithmic scale for the
reflectance axis of the spectrum graph.
Export dialog: Added an
option to round 8 bit RGB data when exporting data. This option is useful
when exporting RGB data for programs which reject the fractional part of RGB
values without rounding.
- Preferences dialog new settings:
- An ‘Adaptive measurements’ setting for
Emission measurements done with the ‘i1Pro / i1Pro 2 (XRGA)’ driver; with
this driver, adaptive measurements can be made with an i1Pro or i1Pro 2.
- An additional ‘SPECTRAL_NM450’ CGATS tag
format to use when exporting CGATS file. This tag format is used by
- System wide settings for the spectrum scale
and the decimal separator.
- Will now record separately the last folder
used when opening or saving different file types (patch file, ICC profile,
- Better uniformity of the Open file dialogs
and review of each dialog’s preferred file formats.
- CxF2 import: Will now correctly import the patches names
and IDs from a CxF2 Palette when the number of patches is different for each
data type within the Palette.
- Patch-Reader window: Corrected a bug where the
Display-Check window opened when clicking on the Patch-Reader ‘Info’ button.
- Version 4.0 is the last version which supports Mac with
PowerPC processors; future versions will support Mac with Intel processors
Version 3.7.0 b275 (2012-02-20)
Added support for the Datacolor Spyder4 colorimeter:
This instrument is currently used in the
Supported models: Spyder4ELITE, Spyder4PRO, Spyder4EXPRESS.
PatchTool can select any of six built-in calibration matrices specifically designed for
various display technologies, and which provide improved measurement
Select between two measurement speeds.
Correction Matrix tool: It is now possible to assign a Color Correction
Matrix to the i1Pro.
- You can now open one or more files with drag
and drop on the main window
'Open file' button.
Version 3.6.0 b268 (2011-12-14)
Added support for the X-Rite i1Display Pro colorimeter:
This instrument is currently used in the
Supported models: i1Display Pro hardware sold by X-Rite (i.e. the retail
version, part #EODIS3-XR). Generic models sold by other companies (third
parties, or OEM, part #EODIS-OEM) should also be compatible. At this
time we cannot say if we will support or not custom models sold by other
companies since separate agreements with these parties may be required.
More specific info will be provided as new models are released.
PatchTool can load and assign calibration matrices (contained in X-Rite
Emissive Display Reference (EDR) files) specifically designed for
various display technologies, and which provide improved measurement
accuracy. Five EDR files are supplied; additional files could be added
in the future without a need to reinstall PatchTool.
Select between two measurement speeds.
Note: On Mac, OS X 10.5+ is required (Mac
Intel tested, PowerPC TBD).
- Display-Check Instrument Info dialog:
Revised interface: You can now assign the
instrument preferences without going back to the program Preferences’
More robust code to improve the connection
to an instrument if this instrument is not connected when the
Display-Check window is opened.
- (Mac) Replaced PICT by PNG as an image
- Exporting images: Fixed a bug where a reddish, yellowish,
or orangish tint could be seen in 16 bit TIFF L*a*b* patches when a* and/or
b* was negative with a value between zero and -0,001953.
- Display-Check RAW file: Now shows correct L*a*b* D50
Source data. The problem was seen when the reference data was XYZ, L*a*b* or
L*C*h* and the destination profile was an external ICC profile. The problem
did not occur for RGB, CMYK, and spectral reference data, and when the
destination was an internal PatchTool profile; as well, RAW measurements
were never affected.
- Now shows the correct Hardware and Driver versions for
the Spyder2 and Spyder3 in the Display-Check Info dialog.
Version 3.5.0 b255 (2011-06-01)
Extract Target from Image tool: This tool is designed to directly extract
the average of target patches in full size photographic images.
Target size: User-assigned ROWS and COLUMNS. The patch fill-ratio is
adjustable. The tool enables adjustments for almost any target
Supported image formats: TIFF RGB (8 bit and 16 bit), and JPG.
Embedded profiles are recognized and automatically extracted.
Extract Profile from File tool: Extract a profile from a TIFF or JPEG image;
save the profile with an ICC or ICM extension. The tool shows the profile
name, type, ICC version, device class, and default intent.
Tweak Target tool: Improve the accuracy of
printed color patch lists by successive approximations. The original color
list is modified in one or two iterations. Important: This tool is NOT
designed to edit or change a profile.
Correction Matrix tool: Determine a Color
Correction matrix between two instruments according to ASTM E1455-2010. A
Color Correction matrix helps improve inter-instrument agreement in emission
(i.e. display) measurements. The matrix is computed by making measurements
of the primaries and white of a given display using a reference instrument
(often a spectrophotometer) and a target instrument (often a colorimeter).
The measurements can be obtained with PatchTool Display-Check, if the
instrument is supported by PatchTool, or data from any instrument can be
entered or loaded into the tool. A matrix is always assigned to a specific
combination of display + target instrument.
Display-Check tool: Now supports the use of
Color Correction matrices. Improve inter-instrument agreement and the
accuracy of colorimeters on wide-gamut displays.
- Import and
Export Adobe Swatch Exchange
(ASE) files. This file format is used to exchange color swatches between
Adobe applications such as Photoshop and Illustrator.
Supported color spaces: RGB, CMYK, and L*a*b* (D50). Because an ASE file
can contain swatches in all color spaces, PatchTool will create separate
files for each color space.
Color groups, such as those created in
Illustrator, are joined at import.
Supported color types: Process + Global
(only type supported in Photoshop), Spot color (Global), and Process;
the color type is the same for all PatchTool exported patches.
- Open TIFF images and assign one patch per
pixel. This tool is useful to open target files saved as one pixel per
patch, as well as small image files.
Supported image formats: TIFF RGB, CMYK and
L*a*b*; all in 8 bit and 16 bit.
Maximum image size: 65536 pixels (which
results in 65536 patches).
- Added “Use the patch Name as the patch ID“
command in the Patch view Tab
Re-map menu and in the Tabular data Tab
contextual menu. This command was added after it was noticed that patch IDs
were now incorrectly assigned to the Name tag in exported CGATS files from
X-Rite’s ColorPort 2.0. After using the command, it is possible to correctly
change the layouts of IT8.7/4 and ECI2002 files.
- Added “Assign the patch-ID as the
patch-Name” checkbox in the “Import CxF2” dialog. In some CxF2 files, the
patch-ID field contains the patch-Name; by checking this box, you can import
the ID field as the Name.
The saved/exported file name is now shown in the file window title after the
file is saved.
- A check is now made on the patch IDs of
ECI2002 and IT8.7/4 files to see if they match the expected values; a
message is shown to the user if the check fails.
Patch view tab of opened files: You can
rename a patch using the alternate contextual menu (Shift + right-click).
Tabular data tab of opened files: You can
rename a patch by clicking in the Name column.
Info window now shows the beginning and
end of long file names.
- Will now deselect any selected Name cell when renaming
the Unconstrained Patch-Reader patches.
- Now properly sets the rows when changing the layout of
ECI2002 and IT8.7/4 files.
- Added Exception handling when opening and re-opening a
file which is locked by another application.
- (Windows) A Display-Check sequence will now stop when
pressing the Stop button.
- Will now correctly interpret CxF2 input values when the
program runs in an international environment where the “thousands” separator
is a period.
Version 3.0.0 b228 (2011-01-10)
Patch-Reader tool: This tool is designed to
measure targets or individual colors in reflectance (i1 Pro only).
Measurements are exported to a CGATS type file for compatibility with most
applications. There are three measurement modes:
Unconstrained measurements: Measure color
patches in any order; select between the XYZ, L*a*b*, or L*C*h* color
spaces. You can re-order the measurements by dragging them in a list;
you can sort, delete, or rename any measurement. Look at any or all
spectrums on a graph.
Custom charts: Define a chart by assigning rows and columns numbers.
Measure the patches individually (Patch mode) or line-by-line (Strip
mode). You can use a timer to automatically trigger a measurement at
fixed time intervals when in “Patch” mode. The Strip mode works with
lines of patches which exhibit a high contrast between them or with
lines of patches which have contrast gaps.
PatchTool file: Select any opened file as a reference. The measured
patches can be visually compared with the reference colors in the file.
The other features are identical to the ones of the Custom chart.
CMYK data can now be assigned to an ICC
profile. When opening a file consisting only of CMYK data, you can assign
any ICC profile to this data. When a file has no CMYK data, you can select
any CMYK ICC profile to convert the imported colors to CMYK. Note: As in
previous versions, when a file has CMYK data in addition with another color
reference, such as XYZ or L*a*b*, CMYK is imported as is.
- RGB data can now be assigned to an ICC
profile in addition to the standard RGB spaces of the previous version. When
opening a file consisting only of RGB data, you can assign any ICC profile
to this data. When a file has no RGB data, you can select any RGB ICC
profile or the built-in RGB spaces to convert the imported colors to RGB.
Note: When a file has RGB data in addition with another color reference,
such as XYZ or L*a*b*, RGB is imported as is.
- Compare files saved from Display-Check
Quick-Test measurements will now re-open with the “xy graph” and “Display
- Export of spectral data in CGATS files: You
can now select between three data tags types for spectral data: nm450,
SPECTRAL_450 (used in ColorPort), and SPECTRAL_NM_450.
When making a test using a PatchTool file,
and when applicable, the tool shows information on the RGB or CMYK
profile that was used to derive the file XYZ data.

types when exporting Compare files obtained with Display-Check.
- Munsell export:
New database which results in better
The conversion speed is typically 2X faster.
- All reports and export files now contain
more information and comments that describe the data in the file.
- Will show a warning message and not an error message when
trying to save a file which is opened by another application, or locked.
- It is not required to restart the program if an Eye-One
Display is disconnected and replaced by an i1Pro, and vice-versa, in
order for the program to recognize the new instrument in the Display-Check
Version 2.8.0 b182 (2010-01-28)
Added a chromaticity diagram
to show the measured primaries locations relative to the ones of standard
RGB spaces. This diagram is generated when performing a Quick-Test with a
Neutral ramp plus R, G, and B ramps.
- A dialog is now presented to the user when a
Version-1 CxF file is not Standalone. The user can select between letting
the program try to parse it, or cancel the import (cancelling import was
imposed in prior versions).
- Display-Check tool: The sections of the Help
manual describing the tool options were rewritten and examples were added.
- Revised the Appendix on Color Management in
the Help manual.
- Now properly retrieves the black level when generating a
report in the Compare window 'Display data' tab; the problem occurred when
doing a Quick-Test with just a Neutral ramp.
- Now properly resets the Minimum and Maximum 'L' values
when clicking on the 'Default' 'Grid options', button of the OSA UCS tool.
- The default choice is now to discard the measured RAW
data after a Display-Check, and NOT to save it.
Version 2.7.0 b173 (2009-09-23)
- Added support for the Optical Society of
America Uniform Color Scales (OSA UCS):
Import UCS color lists defined as Ljg coordinates into a PatchTool file.
Generate UCS color lists for any of the nine
standard UCS data planes.
Export any opened file (with spectral data
or 10 degree Observer data) as UCS coordinates.
- Added “D93” and “E” in the illuminant list.
- Added an alternate contextual menu to the
“Patch view” tab. This new menu can be used to reassign the color of a
single patch (single files and Compare files) or of a range of patches
(Compare files only).
- Minor interface changes in the Gamut tools
window and in the Export dialog.
- (Mac OS X 10.6 Snow Leopard) Fixed a compatibility
problem which made the program crash on startup.
- Disabled Munsell export for files defined only with the
10 degree Observer.

Support for the following reflectance color
spaces: L*a*b*, L*C*h*, XYZ, xyY, AdobeRGB, sRGB, RGB, CMYK, plus
- Added menu shortcuts to folders containing
sample files and IDEAlliance reference files.
- Added a “Recent Open” menu where the last 10
files that were opened can be accessed directly.
- Added keyboard shortcuts to all tools, for
window organization functions, and for the Help file.
- Added the 2009 versions of the ISO 12647-7
reference files in the
IDEAlliance files folder and restructured the IDEAlliance help
- Fixed the contextual copy-data menu in the Compare window
“Patch view” tab, where only the Reference data was copied.
- Fixed the problem in the Average tool where the average
of spectral data was sometimes scaled incorrectly.
- Fixed issues with the previous keyboard shortcuts.
- Now correctly computes the size of the vertical markers,
used to separate patches in a target image, when a change is made in the
resolution field of the Image tab in the Export window.
- (Windows XP) Fixed the problem where some popup menus
would not work properly in the Traditional Chinese version of the OS.
Version 2.5.0 b142 (2009-01-26)
Convert RGB or
CMYK data assigned to a Source profile to a Destination profile.
Convert RGB or CMYK data assigned to a
profile to the Profile Connection Space (i.e. L*a*b*/XYZ).
Convert L*a*b* or XYZ file data to RGB or
CMYK through a profile.
Check if RGB or CMYK data assigned to a
Source profile is
clipped by a Destination profile.
Check if L*a*b* or XYZ file data is clipped
by a Destination profile.
Generate device dependent
RGB or CMYK color
color lists (L*a*b*/L*C*h*/XYZ) with a gamut limited by a profile.
gamut volume of a
- L*a*b* data contained in CxF files (CxF 1.0)
can now be imported (in addition to spectral data).
- The patches width and height can now be
separately assigned when
exporting patches as images. In previous versions, the width and height
were always the same.
Contrasted markers can be
added between patches when exporting an image; these markers enable scanning
of the printed image one line at the time instead of patch by patch (this
feature is designed specifically for i1-Pro instruments).
Export image dialog: The
interface used to specify the patch and image sizes was redone. Also added
“cm” units to the patch and image sizes.
- Will now open CxF files (CxF 1.0) which do
not contain a description of the CxF file structure, also called the
Document Type Definition (DTD), since the DTD is not inserted in the file by
Version 2.3.1 b110 (Mac only) (2008-10-10)
- Fixed a bug that made the program crash on
start-up. The problem was seen on Macs running OS X 10.5.5.
Version 2.3.0 b109 (2008-06-16)
- Added support for X-Rite DTP94 (MonacoOPTIX)
Compare files can be
re-opened within PatchTool for further analysis.
- Now records the measuring instrument Serial
Number in exported files
- There is no more a requirement to be a
system administrator in Windows XP; this change also makes the program
better compliant to Windows Vista security requirements.
- Windows 98 is no longer supported; the last
compatible version for this OS is 2.2.0.
Version 2.2.0 b102 (2008-04-14)
- Added support for Datacolor's Spyder3
colorimeter. PatchTool uses an exclusive adaptive algorithm to speed-up
data-acquisition while minimizing noise. The measurement time is based on
the patch display luminance, and there are two user-selectable modes which
place emphasis on either SPEED or PRECISION.
- Display-Check measurements with the Spyder2
are now done with an adaptive measurement algorithm similar to the one used
for the Spyder3. In SPEED mode, measuring the 1617 patches of an IT8.7/4
target can now be done 2.4X times faster than with previous PatchTool
versions, with negligible effect on the measurements statistics.
- The decimal separator for exported data can
now be forced to a period (0.0) even when the program runs in an
international environment where the decimal separator is a comma (0,0). This
option facilitates data exchange with applications that are not
Version 2.1.0 b098 (2008-03-25)
- PatchTool has a new feature which helps to
fulfill the requirements set forth by
and GRACoL approved papers) and monitor
proofing certification. In particular, when IDEAlliance proofing reference
data of an IT8.7/4 target is compared to measured data, a report can
automatically be generated. This report covers the statistical analysis of
all IT8.7/4 patches as well as the comparison of specific patches of the
chart. More information can be found in application notes
- An IT8.7/4 chart layout can now be changed
between “Measured”, Random” and “Visual”. You can also assign the official
IT8.7/4 patch IDs if they were not in the opened file.
- For ECI2002 charts, you can now assign the
official ECI2002 patch IDs if they were not in the opened file.
- (Mac) New drivers are provided for the
Datacolor Spyder2 colorimeter. The old drivers freeze the application when a
Spyder3, a more recent model, is connected. There is no problem when a
Spyder2 is connected.
- Fixed the issue where display measurements
made with the Eye-One Display, the Eye-One Display 2, or the Spyder2, were
corrupted. The i1Pro was not affected by the problem.
- The program will now react properly if the
previous default display profile is missing at program start.
Version 2.0.0 b091 (2007-12-06)
- PatchTool display output is color-managed and can be set
to use the system default display color profile, a built-in color profile,
or any user-assigned ICC profile.
Measure your display characteristic within
PatchTool using the Datacolor Spyder2 or the X-Rite Eye-One line of
instruments (i1Pro or Eye-One Display).
Export the RAW display measurements for
Check your display performance using
built-in Quick-Test patches. The reference patches and their measured
values are shown in a Compare window. For these patches, you also get a
data” tab with additional comparative data.
Check your display performance using any
color list opened in PatchTool and compare the reference list with the
- Compare tool statistical tab (“Stats”):
- Extract statistical data from compared files
using any color-difference parameter.
- Select between “Absolute”, combined
Neg./Pos., or separate Neg./Pos. statistics.
- Obtain graph and data of the Cumulative
Relative Frequency (CRF), which is helpful in establishing SWOP / GRACoL
- Export color lists in
Munsell “Hue Value/Chroma”
notation. Select the color-difference formula used for conversion. Select
from three output formats (number of columns).
- (Windows Vista) Windows Vista incorporates a Data
Execution Prevention (DEP) feature which monitors how applications access
memory. In most Vista Home systems, the DEP setting is set, by default, to
check only the system programs and services; in this case, even before the
fix, PatchTool started correctly. However, the DEP setting can be changed by
the user, either globally or on a program by program basis, and its default
setting may also vary for other OS configurations. PatchTool did not start
when the DEP was assigned to all applications, or to PatchTool only; this
has been fixed.
- (Mac) The program is now offered in Universal binaries
and Intel packages.
Version 1.1.1 b057 (2007-05-21)
- Fixed the crash that happened when exporting the XYZ data
of Compare files that do not have spectral data.
- Fixed a data corruption problem which affected XYZ data
when sorting the data table.
- Fixed a display rendering problem caused by a combination
of the Lightbox setting with other commands which affect the patches order.
- More robust parser for CGATS and plain text files.
Version 1.1.0 b052 (2007-03-26)
- Compare tool:
Compare two files (with the same number of
patches) in the same window.
Sort patches according to the difference in
any of the following parameters: C, M, Yellow, K, R, G, B, x, y, X, Y,
Z, E*, L*, a*, b*, C*, h*, or H*.
- Import RGB data encoded in 8 bit, 15 bit, 16 bit, or
scaled to 100%.
- Recognizes ECI2002 color lists and can display their data
Measured, Random, or Visual layouts.
- Export RGB data encoded in 8 bit, 15 bit+ (i.e.
Photoshop "16 bit'), "true" 16 bit, or scaled to 100%.
- Export spectral data in either 0-1 or 0-100% ranges.
- Export spectral data with either a 380 to 730 nm range or
a 400 to 700 nm range.
- (Mac) Corrected 16 bit export for TIFF image.
- (Mac) Fixed crashes which happened when clicking on the
top window action
buttons while the program was busy.
- Corrected the cases, for non-spectral color lists, where
data was corrupted when exported to the BabelColor CT&A database.
- Better handling of files which were saved with numbering
formats (i.e. decimal and thousands separators) which do not correspond to the computer’s Regional settings.
- More internal precision that enables handling of 16 bit
RGB and higher accuracy in obtaining RGB values close to zero.
- Faster and higher quality JPEG export. QuickTime not
required anymore on Windows for JPEG export.
- Many other improvements.
Version 1.0.0 b026 (2007-01-03)
- First released version for Windows and Mac.
