I agree that the average prepress person may not have access to any of the
mentioned software (which is odd, IMHO, considering the importance of these
kinds of tools in production -- never mind the price -- but I agree it
requires considerable knowledge to use them; it's like being handed a loaded
gun).
If all the average prepress person can use is Photoshop's modified
Neugebaueur equations for separations, well, as long as it gives acceptable
results to those that use it, I guess there is nothing wrong with that.
As a side note, regarding Photoshop's bundled ICC profile, it'd be nice to
have a little more documentation on them in the form of a PDF on the
distribution CD, to help make an educated decision as to the applicability
of these profiles in one's production conditions. I'd even start by renaming
the profiles to add the fact that "US Sheefed Coated v2" corresponds to a
print run that was made at 175lpi, which I have to thank Bruce Fraser to
mention earlier in this thread -- I would have never known this kind of
insider information, otherwise.
It would help being a little less "blind" when it comes to supplying a
separations for unknown CMYK print conditions like this whole thread started
: "What flavour of CMYK to supply". It'd nice also to know whether the
plates for that particular run were made CTP (linear or what?) or analog
(from film).
I wonder at which stage is GraCol's US sheetfed colorimetric standard
development these days? So much to track and only 24 hours in a day...
