loosing ICC profiles

[christophelesbats]

Hi,

I have some 16bits TIFF files using a CMYK profile (should be ISO Coated V2). I really like the post-processing using xnviewmp which allow to add frame, signature and logos pretty easilly.
I pay attention to select the keep icc profile in the output section as well as in the TIFF output one.
But I realized that resulting files were 8bits TIFF with sRVB profile. I tried on Mac and Windows 7 with the same issue. I gave a command line try using nconvert, and as expected no good surprise.

As I saw some issue with 16bits files in the forum, I gave a try too. Same result: sRVB.
regardless of the 16 to 8bit reduction, It would have not been an issue with a wider profile than sRVB, but when I try to convert from sRVB to CMYK I can see a difference.

Am I the bug, did I miss something (which I hope) or is it a xnview ?


Thanks in advance,
Regards,
Christophe.

XnView or XnConvert convert always picture into 8bits by component RGB.
nconvert can work in 16bits.
