Example: Vender receives an ad from client that will ship to three
different publications. All images are separated into U.S. Web
Coated (SWOP) v2 which is a 22% Tonal Value Increase and a 300%
Total Ink Density spec. However, each publication requests a
different separation.
a) 'Bobs Motorcars' asks for TVI:28%, TIL:260%.
b) 'Retirement World' specs TVI:22%, TIL:280%
c) 'Mens Perspective' requests TVI:20%, TIL:320%.
Since each publication requests a SWOP certified proof it is fair
to assume that I can separate into a TR001 spec'd profile provided
that it was set to the specified TVI/TIL requested by the vendor.
I am also aware of age old prepress preference to create pure K
drop shadows which kills any chance of a completely automated ICC
workflow. However, any advice or insight to this very practical
problem would be welcome.
Kevin,
Using a colorserver like Alwan CMYK Optimizer (www.alwancolor.com)
which utilizes device link profiles, allows to preserve primary and
secondary colours so you don't get "contaminated" shadows or primary
colors. It also has a simple dotgain adjustment control and a way of
analyzing each image based on TAC with automatic reduction of areas
surpassing a defined tolerance only - with no apparent change of
color. Using these last two functions would probably be the easiest
way to get from A to B in the above case. And it can run completely
automated to convert separated PDF's. There are other device link
tools on the market but I don't know of others that actually analyzes
each image AND has dotgain controls...
