custom chart mode

previous previous screenshots home screenshots home next next previous previous screenshots home screenshots home next next
In the Patch-Reader Custom chart mode you select the numbers of rows and columns of the chart or target you want to measure; there is no need to open a file of the proper size beforehand. Click on the "Start" button once the chart dimensions are defined. You can select any patch to make individual measurements, or use a timer to automatically make measurements at fixed time intervals. It is also possible to take measurements one row at a time, by scanning the instrument from one side of the chart to the other. Select the Strip mode with the menu within the “Measurement mode” box; the contrast between neighboring patches must be high enough so that the instrument automatically detects a transition OR the patches must be separated by contrast markers consisting of thin black and/or white bars before and after each patch (Note: Targets with contrast bars can easily be created with PatchTool). Click the “Stop” button at any time. The measurements are saved in a CGATS type file which can be readily opened by PatchTool and most programs which can read color files.
Once patches are measured, just move the mouse over a patch and see the measured data displayed in the top of the window. On the screenshot above we see L*a*b* and density data (Status T, as selected in the Preferences dialog). The displayed data type can be selected with a menu which opens with a right-click over any patch. The “Measurement mode” box has options which may or may not be available depending on the connected instrument. Please consult the Help manual for more information on the various measurement modes available. 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 "Unconstrained measurements" mode are shown on the previous page. Screenshots of the "PatchTool file" measurements mode are shown on the next page.
