Hi Elle, Profiles seems ok, and tifficc and other programs read them just fine. May I have the " red-no-alpha.tif" tiff file? It seems to me this is the source of trouble.

So I'm wondering if there might be a problem in tificc itself. Does tificc actually support conversions to XYZ? Here's the command line I used with a sample image called "red-no-alpha.tif": tificc -w32 -i sRGB-elle-V4-srgbtrc.icc -o XYZ-D50-Identity-elle-V4.icc red-no-alpha.tif red-tificc.tif The two profiles can be downloaded here: https://github.com/ellelstone/elles_icc_profiles and are located in the "profiles" folder. The code snippet that generates the XYZ profile is as follows: profile = cmsCreateXYZProfile(); cmsWriteTag(profile, cmsSigCopyrightTag, copyright); description = cmsMLUalloc(NULL, 1); cmsMLUsetASCII(description, "en", "US", "XYZ-D50-Identity-elle-V4.icc"); filename = "../profiles/XYZ-D50-Identity-elle-V4.icc"; cmsSaveProfileToFile(profile, filename); cmsMLUfree(description); Thanks! for any help in figuring out what the issue is, whether in tificc or in the profile (or both?).
