Color Measurement
and Analysis
PatchTool PATCH-READER TOOL
unconstrained mode
As shown above, the Unconstrained measurements mode is one of the three modes available in Patch-Reader. If using an i1Pro 3 Plus,
select the measurement head you intend to use before starting the measurements; the “Std. head” is used for taking measurements in the
M0/M1/M2 conditions. Once you click on the "Start" button you can measure color patches in any order. When available, you can select
different M0, M1, and/or M2 measurement condition for each measurement. A single click can give you the fluorescence characteristics of a
paper as show by measurements #1, #2, and #3 in the screenshot below. Select between the XYZ, L*a*b*, or L*C*h color spaces (in addition
to spectral data) and get the reflection density as per ISO 5-3. You can re-order the measurements by dragging them in the table; you can sort,
delete, or rename any measurement. You can also look at any or all spectrums on a graph.
You can click the “Stop” button at any time. If you decide to keep the measurements, you are presented with the CGATS file options dialog that
presents options to be used for saving the CGATS compatible file; this file can be readily opened by PatchTool and most programs which can
read color files. Screenshots of the "Custom chart" and "PatchTool file" measurements modes are shown on the following pages.
