I feel the need to jump in and say what no one has really said
explicitly yet. Proofs are not just for color. To varying degrees, some
people have mentioned some of the reasons that printers prefer dot
proofs. Unless I've missed a post or two, everyone who talks about dot
proofs has talked about making Approvals, or some other electronic
simulation of a dot proof and the pros and cons of simulations.
I would argue that dot proofs, made directly from the same film that
the printer will print from (i.e. analog dot proofs, not digital),
still have intrinsic value in predicting behavior on the press and are
able to provide confidence about certain things that no digital proof
can currently provide.
Until there is a reliable way to guarantee (emphasize "guarantee") that
the RIP that created the digital proof (continuous tone inkjet,
Approval, or whatever it may be) and the RIP that is on the press
(whether CTP or simply the printer's RIP to make the film), will
produce the exact same output, analog dot proofs still hold value. Even
if you are providing both the digital proof AND the film, it is still
possible to overlook differences if the exact same RIP is not used to
make both. It's happened to me. The digital proof looked great, but the
film had a postscript issue where the RIP for the imagesetter caused an
error which was difficult to see in the film without an analog proof.
This went to press and was in stores before it was caught (it was a
packaging job).
Anyone who outputs to a RIP knows about the myriad of issues that must
be handled on a job-to-job basis and the many potential pitfalls. I
think printers would more quickly embrace digital proofs, dots or
no-dots, if there could be some guarantee about the consistency between
the RIP that made the proof and the RIP that will send pages to the
press (CTP or imagesetter).
For the record, I'm not opposed to digital proofs. In fact, I prefer
this whenever possible. However, I still see value in analog dot
proofs--particularly when the RIP becomes an wildcard.
