A basic guide (see post #1) to setting up ARGYLL CMS profiling on your computer

i didn't do a nozzle check before the target, my machine is still working daily and not on idle, i just execute a nozzle check and it is fine. thank you i will be waiting for the new target, and i saw the post on jtoolman group about you sizing the target in photoshop for the i1studio could you explain that to

You might have at try with this target (It might be same you have downloaded

I have also included a smaller target that does not need the special Colormunki/i1Studio 3D printed jig to be scanned successfully: The 325 patch Colormunki target can be scanned like this:

does the 350 patch create a good enough profile or the 480 patch is still the magic number

Modern RGB printers are pretty linear in behaviour, so there is not much difference between 325 and 480 patches, but for shadow details a larger patch size can certainly help. Just give it a try and see what does better: 480 vs 325 patches.

This is the chart after i scan both 480 and 325 profile. In the scanning process there are still warning about DeltaE on both patch but the final test image are the same just a little brighter on the 325 profile other than this it the same

Take into account measuring errors. Like I have said there is little difference visually in prints, which you want to have. But have good look at the shadows (not crushed) if there is any difference when printing the same picture.

Friends, please, I really need your help. For more than two months now I’ve been trying to create a profile for Epson L8050/L18050 6-color inkjet printers using a ColorMunki Design and ArgyllCMS. Profiles made in the native i1Studio software turn out bad (sometimes too yellow, sometimes too red). The ones from ArgyllCMS are better — but still not perfect.

I’m using these commands:

targen -v -d2 -f720 -G -g50 -l330 test
printtarg -v -p A4 -t -L -a "1.2" -m "5.0" test
chartread -v -H -T "0.4" test
colprof -v -D"profile_name" -q h -i D65 -l 300 test

A bit of explanation: in the colprof command I use the parameter “-l 300” because with any other value the image gets a noticeable beige cast — the whites are not truly white but light beige. It’s visible even in the print preview. Only “-l 300” makes the white close to true white (#FEFEFE).
Also, without “-i D65” the image becomes too yellow. However, even with these colprof settings, I still can’t get perfect colors. Now the image seems to shift slightly toward pinkish-blue tones.

Standard printer profiles are using the D50 observer at 2 degrees (1931_2) thus:

colprof -v -qh -i D50 -o 1931_2 -S AdobeRGB1998.icc -cmt -dpp

Using this method you will have to put a copy of the adobe1998.icc in the working directory (where you type the colprof command), otherwise the process will halt after a few seconds.
