Hi Dimitrije Do You have the particular reason to compute high resolution backward table (-bh) having standard resolution of the forward table (-qm)? I didn't know wither it is the problem reason or not but... As I'm understanding the profile compute process, the backward table compute is performing on the forward table compute result. So, If You have normal resolution forward table, there is no sense to compute higher resolution backward table. As I've noticed, the computing of the forward table is much more faster than the backward one. So You can try "-qh" or even "-qu -bh" without very much computing time increase.

I have the same problem on several printers. Command is always the same: "colprof -v -D"name" -qm -bh -cmt -dpp -ssRGB.icm -Oname" please advice Dimitrije Zivkovic
