I1P has no problem with custom charts per se; I believe Terry's difficulty was in getting it to compute a profile from a data set that either lacks any CMY+K patches or has too few to satisfy i1P', which evidently errors out. I1P is not a true n-color solution; it wants to see a full CMYK set. (I have not tried making an RGB profile with it using C,M, and Y--maybe that also causes an error). Other profilimg applications have been designed to make profiles with any number or combination of colors and don't reqiure CMYK at all. Profilemaker Packaging was one. ColorLogic CoPrA (all versions) can make CMY profiles. It also should have no trouble using a chart with fewer-than-usual CMY+K patches. Mike Mike Strickler MSP Graphic Services

Unfortunately, i1Profiler needs to see some CMYK+K patches or it errors out. Tried adding a few K-only patches but that didn’t help.
Argyll’s targen & printtarg can generate CMY-only test data and charts in seconds.
I know that you (really annoyingly) can’t import custom charts for scanner profiling, but surely i1Profiler must be able to import custom charts for printer profiling?
