When creating profiles for printing presses, or proofing systems that
will effectively be a "press", how do you create the test charts for
optimal results (in our case with Monaco Profiler). I think it should
depend on the type of printing process you're emulating/profiling. For
instance, with sheetfed vs. web on a Polaproof:
I assume we would want to set up our ink limit on the patch charts from
Monaco Profiler to correspond to acutal printing conditions. In other
words, limit the targets to a 325% total ink for sheetfed work, and
300% for SWOP proofs (actually SWOP spec says that small, non
detail-critical images can have up to 320% total ink coverage).
I ultimately think we'll need at least two profiles: a "generic"
sheetfed profile with 325% TIC and normal gain curves on a bright white
#1 paper, and another "generic" profile with 300% TIC and higher
(SWOP-spec) gain curves on 60# Monterrey Gloss (approved proofing
paper) for magazine/catalog/web work. (If we went to the same press
every time, we'd want to profile that, but we send work all over the
country and have to shoot for "average" conditions.)
Which brings up an interesting side-question, how do you reconcile the
SWOP-spec allowable variance of 300% or 320% TIC depending on the image?
From a patch-generation standpoint, is there an advantage to printing
with scrambled patches and if so, when?
And finally, what quantity of patches should be used; is there a point
of diminishing returns with too many target colors or the more the
merrier?
You suggestions will be definitely appreciated.
