Hi Listers, thought I'd finish this up along with a
reply to the "Files for Digital Photographers "
post...
"If I nail the contract proofs, I leave the pressman
to do his/her
job. If
they can't, it's not my headache."
Yes, you can take this approach, but again, you may be
basing your color quality on a proof that has
significant dot gain and hue (wet trapping) error
because it is not accurately programmed to simulate
their press. Results may be disappointing.
For general work, Andrew's approach of using a good
proof profile is correct. Digitize your image with a
valid source profile and use a good prepress proof
profile to go to CMYK. Then fine tune the highlight
size and midtone if necessary for the paper and press
type. This usually yields a good looking proof and
then it is up to the pressman.
A press profile is the best answer because now you
have data on what your final destination is. Now you
can properly process your image for that CMYK
destination and feed that data back to your proofing
device for an accurate simulation of that press.
Most printers do not want to take this approach. Some
stick with SWOP because they are publication printers
and some say profiling does not work because all
presses are different. Many would rather have the
pressman chase the results of the Almighty Press
Proof.
A case for the ultimate printing experience:
Bill Atkinson wanted to publish his amazing mineral
images and was aware that standard SWOP printing
conditions would seriously limit the wide gamut colors
of his images.
He offered several US printers to color manage them
for a wider gamut (using four colors of ink) and set
up an accurate inkjet proof.
None of them believed him or were interested! They
said they could do the job well with their existing
four color system.
So, Bill went to Japan and established a system for
printing with four colors of ink and had his book
successfully printed. (Within the Stone

The Japanese company is establishing this method
company-wide and estimates production savings in the
seven figure range.
Bill is very happy with the results and the printer
has streamlined their production and offers their
clients a wider gamut.
I have offered to set up this process to two American
based printers and they have shown no interest so far.
