Welcome to the real world of commercial printing!
Let's clarify here... if you, or your client are going overseas for
printing. you are looking for "cheap". Cheap means to put as little ink as
possible on some crappy Asian paper. They are not there to hold your hand
while they print your job.
As a commercial printer, here in the states, we "profile" (and that is why I
am a member of this group) our files to cheap printers (Epsons & HP's) to
get a reasonable match contract proof. When I say "cheap", that is in
comparison to running the very costly Kodak Approvals, Digital Matchprints,
or Imations.
Of the 2 or 3 high-end commercial printing workflow systems on the market
today, I know of none that pay any attention whatsoever to embedded profiles
(sorry guys). If your print vendor has told you otherwise, he is lying.
As to the ink standards, although there are in fact differences, you would
hardly be able to recognize the difference between any of them on press. The
exception to this, are specialized inks, such as packaging inks that are
required to be made with hi rub and fade resistance, and are in fact very
"dirty" in color. This is compensated for using a proprietary RIP profile
for those specific inks to alter the plate output.
Dot gain, ink limits, UCR, GCR, Trapping, its all done in the RIP at the
time of plate output to our specifications... and of no concern whatsoever
to the files creator.
The deal with the .eps files... My guess here is that they are running a
Rampage front end system that requires all pages to be converted to .eps
files (with tiffs & fonts omitted). If they could talk you into doing it for
them, its one less step they had to handle.
We turn lots and lots of files and images on a daily basis, and a good
percentage of it is high end work. Of those files, 99% of the clients don't
care what they send us... they just want a printed sheet that matches the
proof we made for them and their client approved. For the other 1%... that
are interested in the "hows" of the process and want to make their files
better, I'll work with them to help them achieve that goal.
Hope I didn't scare anyone here... but this is how it really works. We put
on the "front" to our clients about "fingerprinting" all of our presses and
calibrations, profiles, etc etc etc. just for their jobs. But its all
really only done once, and if nothing major changes, our RIP to plate
profiles don't change... and haven't in quite a while. We make the call
based on the job, subject matter, and paper it is running on etc. On the
web... we hit the UCR hard to save $$$ on the ink and let us run at higher
speeds. Overall, we just categorize the job when it comes in and thats the
RIP profile it gets. Sounds too simple, but it works.
