I have a question about a profiling run we are going to be doing in a couple of weeks. First a little background in case it helps, we have one sheetfed Heidelberg press, print using G7 process, doing a new calibration\profiling run after everything being reset on press and new inks being used, I use Profilemaker and plan on doing a profile run also just to see if I get a better proofing result using a custom profile instead of just using the standard Gracol profile in the proofer also.
Anyway, my question is as far as number of patches go when profiling, is more always better? I ran across the larger targets that Bill Atkinson has on his sight, the biggest having 6,048 patches! I could use this for a proofer profile but don’t have room for it in one pass on our 1/2-sheet size press. So would it be beneficial to make 2 press runs to get all this 6k patch target or just use the smaller one that will fit on our sheet size which is 4k patches. When you compare the ECI target I’ve used in the past with 1700 patches, these just seem to have so much more to measure, but will the profiles be that much better or does Profilemaker make better profiles with more patches?
Any and all thoughts appreciated,
