The task (Win32): Camera shots: outdoor, in AdobeRGB1998.icc space; Inkjet printer profile: HPED2880.icc; Desired mapping methode: perceptual. There is mMy workflow as I understood from ArgyllCMS docs: 1. tiffgamut -ia -pj -cpcd AdobeRGB1998.icc Shot.tif as result gives Shot.gam. As for -i key, tiffgamut document says: "NOTE that if you are creating an image gamut suitable for use with the collink -g or -G flags, or colprof -g, use the Jab appearance space intent for appearance space gamut mappings, and the same input viewing conditions to be used in collink or colprof using the -c flag, i.e. "tiffgamut -pj -cmt sRGB.icm image.tif". So I use default intent -ia (absolute). If I'm right, there is -cpcd input viewing condition. 2. collink -G"Shot.gam" -ip -cpcd -dpp AdobeRGB1998.icc HPED2880.icc Shot_lnk.icc as result gives link profile Shot_lnk.icc. 3. cctiff Shot_lnk.icc -d HPED2880.icc Shot.tif Shot_prn.tif as result gives TIFF image for direct printing. But I've seen the same in ImgTarget-013 (equivalent record) 1. tiffgamut.exe -ir -pj -cpcd AdobeRGB1998.icc Shot.tif why -ir, not -ia? 2. collink -G Shot.gam -ip -op -ip -cmt -dpp AdobeRGB1998.icc HPED2880.icc Shot_lnk.icc why two -ip? As I understood from the CMS documentation, in gamut maping mode the -o key isn't used at all, as it for simple mode exclusively IMHO. Am I right? There is clear division between simple and gamut mapping modes in colllink.htm. So the questions: which intent I need to chose in tiffgmut? And is there the -o key needed in collink gamut mapping mode?
