John,
Wouldn't the "two profiles" method yield acceptable results for those that
don't do as much lamination as you do? I mean, you seem to do a fair bit of
laminated work since you've gone to the trouble of installing a small
laminator on press so that the pressman can compensate, during make ready,
for the effects of the lamination. I was thinking that, perhaps, for those,
like my client, who's not as sophisticated in their approach, could the "two
profiles" method have a remote chance of working, in your view? Since that
must have been, as you describe, the approach you necessarily took at the
beginning of doing laminated jobs?
