Andrew,
That's a thought, to average different sized patches. The thought wouldn't
have occurred to me I must confess.
Do you find printers you work with naturally inclined to give you lots of
press time (and paper) so that you can average lots of press runs for
developing press profiles?
We all have differing practices. The printers I work with resent the very
idea of having to give up on press time and paper to allow press profiling,
regardless of the mess they can be in with regards to color matching. Unless
they have a big client who's putting a gun to their head. Then, they're
willing to listen a little more. But I haven't succeeded in convincing
anyone about the necessity of averaging multiple press runs for the sake of
press profiling. Printers have tough attitudes. I'm curious about your
experience.
I agree it's all about variability.
Roger

That's what we do when profiling presses. Additionally we use two sets of
profiles with differnig sized patches (smaller and much larger). Then
average lots of press runs.
