TIF CMYK to JPG RGB conversion color issues

Post by CybrMike »

Ok, been working on this a couple weeks now and have some questions.

IM VERSION: ImageMagick 6.7.2-3 2011-09-07 Q16
Example TIF FILE: http://beta.posters2prints.com/TR2780.tif

sRGB profile: http://beta.posters2prints.com/scripts/ ... caling.icc

This TIF I believe (according to identify -verbose) has an embedded profile, however
If I run:

convert TR2780.tif -profile sRGB_IEC61966-2-1_no_black_scaling.icc sRGBtest.jpg

http://beta.posters2prints.com/sRGBtest.jpg

The result is a JPG image with an embedded sRGB profile, that has a CMYK colorspace (the image looks like a perfect conversion though on my mac). Why is the image CMYK instead of RGB?

So, I though maybe I'd extract the profile from the TIF image and use that:

convert TR2780.tif -strip -profile extractedprofile.icc -profile sRGB_IEC61966-2-1_no_black_scaling.icc TR2780.jpg

http://beta.posters2prints.com/TR2780.jpg
The result is indeed RGB but the colors are just a bit off (close, but not perfect). Is there any way to get a perfect sRGB match from a CMYK image?
