APhoto V2 - color conversion RGB to CMYK wrong (absolute colorimetric) ?

[cgidesign]

APh V2 trial on Windows 10.

All ICC profiles set correctly in Windows Color Management.

Issue:

Converting sRGB TIFF to CMYK ISO coated V2 gives wrong result (using absolute colorimetric rendering intent - not yet tested other conversons).

Correct conversion is shown in ColorThink Pro (a scientific color management analyzing software).

Is there something I am missing or is this just a bug in V2 (and V1)?

Test with relative colorimetric intent - this one looks good. It does what I would expect it to do.

Probably related ?

I guess so, but only Serif knows.

Hi @cgidesign,

As @NotMyFaulthas pointed out, this is related to another issue with colour handling ect.  It is logged with the Dev team for now all i can suggest is you use the workaround of using relative colorimetric to get the correct results.

I've updated the report with the Dev team and linked back to this thread, so we can update you when its been resolved
