[Tool] ChromIQ – a macOS and Windows GUI for ArgyllCMS printer profiling (v3.13.0-beta)

with beta 110 i don't get the Strip labels

i also reset to defaults from the menu, but they didn't appear

Restore to defaults doesn't bring Strip indicator style to default one

When I look at your screenshot the labels are on. Just seems that you made the font very small. Go into the settings window to change that back.

I am experimenting with the scanner profiles. At this moment the profile name is based on the initial name of scanning the target with the spectro. let's say we call it "Moab_Satin_240_gsm_ET-8550_EPG_standard"......the corresponding scanner profile name takes the same name: this is very confusing. Better option: a pop-up / entry form so you can give the corresponding scanner profile (derived from scanning the printer target) with totally different name, for example "Epson_ET-8550_scanner_profile" and then you can save this profile/install the driver in the %system%\system32\spool\drivers\color\ directory for windows (and the corresponding colorsync directory in MacOS)

I also discovered that the external *.icm profile name for scanners does not correspond with the internal name (internal names takes the working directory as base). I had to use a ancient program that can change the internal *.icc/*.icm name (changediscription.exe) to a logical name. Just changing the external *.icm name to your desired name is not enough: the internal name is displayed when choosing the profile in your scanner driver making it confusing.

OK, here an example how good the scanner profile works on my Epson ET-8550 scanner.

Left: scanned without color management (in order to generate the scanner profile) and on the right the scan with the dedicated scanner profile (based on the scanned target (ti3 file) with my i1Pro2 in ChromIQ):

Much better than my old modus operandi using the Eye-One Match3 method with the vintage i1Pro1 that actually is based on the same principle. Scan the supplied scanner target with the i1Pro1 to determine the exact colors which are saved as a reference:

Afterwards: scan the target on your scanner without color management to obtain a tif-file and match the scanned image with the measured values of the same target to generate the final scanner profile.. This target has only 288 patches and 480 patches significantly improves color accuracy.

So one more thing successfully improved

You can now choose your own profile name at the very bottom of the tool by the way.

You can even create a multi-page-target for this process with as many patches and as small patches as you want (as long as your i1Pro is able to read them). Then measure and scan each chart and create the profile out of them.
And, for the next beta, the printer can also be profiled using the scanner as instrument, similar to what PrintPrism does.

If for example you use your 1944 patch target to print and measure a large target for the scanner, then make a scanner profile from that… Then you can try to profile the printer using the scanner as instrument (f.ex. by using one of the two new scanner preset charts for A4 / Letter (more than 3000 patches). Then we could compare the output quality with PrintPrism and using a i1Pro. That would be a very interesting comparison. If a scanner can be used with good quality in this way (by profiling the scanner really well) then the repeated profiling of a printer can be done much faster using the scanner. It all depends on the output quality though
