For one thing, on the free site I use: rgb2cmyk.org, I have always selected the SWOP2006 CMYK output format which I can't find in the CYAN software.
I did an explanation some time ago, well before Gimp 2.10.32 which has introduced a snag.
A good question about adding your own .icc file. First time you run Cyan.exe as well as installing the Gimp cyan.py plugin it makes a folder C:\Users\your-id\.config\Cyan\icc. Put your .icc profiles there.
The SWOP2006 icc you can get from here: https://www.color.org/registry/SWOP2006_...3v2.xalter
A new explanation using Win 10, Gimp 2.10.32 and Cyan 1.2.4 https://youtu.be/D6unCeSgvZk 4 minutes duration.
When it comes to importing a CMYK file into Gimp 2.10.32 Cyan plugin no longer works. The Gimp developers have 'improved' the tiff format and broken Cyan. However the devs have also improved the regular import and most CMYK images will open. Still as RGB, Gimp is a RGB editor.
I use linux and Cyan 'Import' still works here, although complains a bit. And complaints, I thought I had escaped hayfever this year, no such luck, just managed that little video without sneezing
Hello again and thank you so much for your help.
I have downloaded the CYAN plug-in on my desktop and it someow downloaded itself automatically in my GIMP.
Somehow too, the SWOP2006 icc profile that I downloaded installed itself automatically in CYAN since it now appears as a choice.
Following your instructions, I have downloaded an image in GIMP and then in the CYAN plug-in there exported it into CYAN software.
So far so good but:
1) Once the image is there, once I have to put the SWOP2006 in the OUTPUT window what choice do I have to put in the INPUT window? (I have put sRGB (built-in)
2) I have left the GRAY, MONITOR windows respectively on "Select..." and "None". the INTENT window "Undefined" and the BLACK POINT window "blank".
The problem being is that the CMYK.JPG exported from CYAN seems to be exactly the same as the sRGB image imported.
I have also compared my CYAN cmyk image with my RGB2CMYK.ORG image and they are different so something is wrong somewhere in the convertion.
Do you have a link to the IMAGE MAGIK site so I can check to be sure?
Thank you in advance.
