Maybe I will try cctiff at a later time, but how should I print the image without Gimp?
Well, how did you print the characterization charts? The idea is to do the conversion to printer color space manually, with cctiff, and then to print the converted image in exactly the same way (w/o color mangement) as you did print the characterization charts, in order to rule out workflow issues/differences. Btw, regarding gimp, I remember that in the past old versions of the gimp print plug-in did fiddle with the colors during printing, i.e. the DeviceRGB numbers sent to the printer did not match the RGB numbers in gimp's working space. I don't know, however, whether this still applies to recent versions. Best Regards, Gerhard
