Display colors correctly for CMYK images (tif, psd)?

Postby eliio » Wed Jan 18, 2017 7:48 pm

Is there any plugin or addon for displaying CMYK colors in images correctly (mostly in tif's and psd's)?
Now colors look different and oversaturated. Here's the sample (correct is on the left):

Which program displayed the left image? Do the wrong colours appear in all images viewed with XnView?

Gamma correction
You can force XnView to apply gamma correction when viewing images. Could you please check the setting in Tools > Options | View > View | [ ] Use gamma correction? This should be deactivated unless you want XnView to apply some gamma correction when viewing any image.

ICC Colour profiles
TIFF and JPEG images may contain ICC colour profiles. Perhaps using the embedded colour profile may provide better results? You can activate the usage of colour profiles in Tools > Options | General >> ICC .

Please note that these are just guesses.

Welcome to the forum, eliio.

It's a known issue.

Could you please give XnView MP a try? It uses Little CMS: Tools » Settings... » General » ICC

Little CMS (FAQ » How can I use Little CMS in my apps?) wrote:Less common usage would be to convert from RGB to CMYK accurately, to convert separations done for one printer to another printer, to use CIEL*a*b as working space, to read Lab TIFF, to characterize Colorimetric PNG, etc. etc.

This particular image is from Photoshop. But every program (Illustrator, InDesign, CorelDraw) that can handle with CMYK model show pretty similar results.

Thank you, it really helps. I just checked "Use ICC Embedded Profile" without selecting any profile and the default ICC Profile is None.
But this solved the problem. Now the colors of CMYK and RGB files (tif and psd) look the same and correct (both thumbnails and previews).

Thank you, I will definitely do.
