I have always felt that if a proof simulates a density and
a gain that is achievable on press and that the press
should be able to match the proof. Before you get
excitedread on.
The sticky issue is that inkjets and other types of
proofers are not always linier devices but they can be
made to be. I also see lots of un-reasonable proofs
pass my desk. There is a lot of misunderstanding of
how a wet on wet web press can do. The issue also
stands that multiple proofs can be all over the place
and still be within SWOP standards. How is a press
going to match these proofs when they are sharing the
same conditions that are dictated by the same
adjustments? How does a press know when they can
trust your proof? How or they to choose one proof over
another for that matter? How are they to match gain and
density when density is a variable of the gain based on
their press? SWOP is too loose when you are dealing
with over 20 web presses being run by three large
international printers.
The problem I am running into is a way of quantifying
what a press should be expected to do and how much
is too much to expect of them. Presses are set up as a
mechanical process and are ran by lots of subjective
operators. Not to mention the analog nature of the
mechanics of lithography, Gravure and Flexo press
methods.
Profiling for hundreds of presses is virtually impossible
without an organized system of profiling and strict
application of those profiles. This would demand strict
management of the press facility. No one likes a pushy
printer. Do you demand tighter press conditions? No
Press likes a pushy customer. Another question is who
is paying for all that. My company does not want to. They
want predictable presses that fall within a predictable
window of press conditions. But how do we define
those demands.
This falls back to the standard that Terry has
mentioned. We used to be able to do all this with match
prints etc. This was basically because they were
considered trustworthy. I for one know that they too
were flexible but not as fixable as a litho web press.
Now we need a way of quantifying the needs of the
press and narrow down what we are supplying to them
so they have a target. As strict as it is SWOP is, it is too
loose for the kind of matching that is now expected by
most of us.
My long winded two cents
