They're not, that's part of the problem and that's why I'm there!
Matching Pantone Process builds is an even bigger problem than supplied
separations.

I do a lot of press OK's and fingerprinting (when necessary) as our companies
do a lot of prepress work for catalogs and packaging. In the last 2 years all
of the printers we have been dealing with have now gone to CTP. One of the
real reasons for printing linear is the fact that most printers have more than
one press to concern themselves with. As you all know presses are as different
as people are. I have helped a few printers with their installs of CTP systems
and a majority of the time linear has worked the best when trying to balance 3
or more webs or sheet feds. If you had different curves for all the presses,
things could get VERY confusing when they got busy or jobs had to change
presses at the last minute. This has been said before but optimizing the
presses prior to making digital plates is the path to follow. In some cases
only a slight push curve (2 to 4% for sheet fed) was necessary to balance all
presses (web and sheet) AND be able to reproduce the legacy files along with
new files.
This process does take some time and paper up front, and with the ink maker
and press mechanic present the presses can be brought into some alignment
using a linear plate (same as made from linear film). In the long run it will
pay off with faster make-readies and much better sheet to preproof matching
and that means more money in the printers pocket. The printers that also carry
on a strict maintenance and upgrade program (blankets, rollers etc.) quickly
rise to the top when quality becomes an issue with clients and new clients
looking for a good printer. Our separations are typically made to either a
SWOP or GRAcol standard as generic as possible and a majority of printers have
little or no trouble with them on press. In a majority of the catalogs we
prepare there are files that are at least 3 to 5 years old, new digital shots,
and in some cases new scans.
