Hello everybody and happy new year
I am asking here: Cyan is integrated with Gimp.
I need to convert RGB to CMYK for printing.
I wanted to use Cyan or Krita, they seem equivalent.
I found something very odd to me, so after a lot of tests, imho the issue is that
whatever the optional settings, with the exact same conversion to CMYK, tif and jpg :
a difference of about 95% exists between the jpg and tiff versions
(using a very consistent application)
The two CMYK versions, tif or jpg, are not even similar obviously. Even visually.
Many other tests suggest that this cannot be caused just by jpg loss of quality.
I would use the tif format, but this strange total difference seems worrying to me.
No idea if somebody way more knowledgeable, can suggest something.
I emailed the developer of Littlecms, but I don't know if they will clarify.
Maybe somebody can just confirm that the tiff version should be correct enough?
Btw, the only format producing an output equivalent to tif, is Photoshop, psd format.
Also, the result is the same with Krita or Cyan. I think they use Littlecms.
Thanks for any help or suggestion and best
