Up to this point, I have been using a 2 page 1053 patch target (I added 50 patches to an existing target) with PM 5 (probably upgrading to i1Profiler) and it seems to be working well. Would be interested to hear what Michael and Jeff have to say on the subject of profiling with X-Rite software.
Ideally, 16.7 million color patches. Then there’s no extrapolation used to build the profile from the measured data. Obviously that would take a bit of ink, media and time <g>. The profile itself would be huge.
Depends on the software, instrument, device being profiled etc. I’d rather use 1485 patches, two sizes per target, rotated 90 and 180 degrees and from a few dozen pulls off a press than one target with one patch size that has 10000 patches! For an ink jet, 1500 to 3000 is usually going to do the job, there’s a point of diminishing return.
