[Solved] Wrong colors in image - CMYK/ICC

[lian]

Hello, I don’t get the good colors in particular file when resizing with NConvert. No problem with XnViewMP or XnConvert - à droite les bonnes couleurs.

Your image is CMYK, are you including theses switches in your code?

Code: Select all

-ctype cmyk 	  : Channel Type (Raw)

-cmyk_space		: Convert if possible in CMYK space

I haven't actually worked with CMYK files myself so you may need to experiment a bit, and I'm not sure whether -ctype is only relevant to Raw files.

(Edited).

Thanks for quick answer. I will take a look.

Thanks again. I had to add to get the exact colors and keep ICC profile

Code: Select all

-keep_icc -icc

I had to add to get the exact colors and keep ICC profile:

Code: Select all

-keep_icc -icc

In addition to using one of the CMYK switches, or was it not necessary to include either?

Could you post an example command line that works, which might help someone else in the future?

I use to resize to 1200 px the longest size:

Code: Select all

-ctype cmyk -cmyk_space -keep_icc -icc -ratio -rtype lanczos -rflag orient -quiet -resize longest 1200 -out jpeg -o

Thank you for posting your example.

I wonder if the -ctype cmyk : Channel Type (Raw) switch is needed for a JPEG input, but it works anyway...
