Yes, indeed they are. We're continually getting in files to print from
designers who refuse to understand that a tint of a Pantone color has
no reference for a proofer or printer that doesn't actually use
Pantone color inks in its process. Another issue is where they've
taken the trouble to convert the PMS color to process equivalents.
Those numbers may not be the same from different programs depending on
the assumptions in the color management within each program.
Yep! Beware of InDesign CS 2, and Illustrator CS 2 users specifying
colors using the solid libraries when you know full well they have no
intention of printing a job as spot. Those libraries are now LAB based,
and if the user converts them to CMYK, they will be based on the
Document CMYK profile, not on Pantone's builds. A conversation with
their printer notwithstanding, they are better off leaving them as
spot, and letting the printer convert them to process.
If it weren't for the fact applications drop the Pantone reference as
soon as something is now defined as a process color, it would be
possible to parse these files and swap out CMYK values based on actual
output conditions. But since the Pantone reference is lost, it's a
tedious process to do this. Leaving everything spot allows these
objects to be handled much simpler. OR, just don't rely on solid to
process conversions at all and use RGB or LAB based solids with Proof
Colors enabled (Adobe apps), or Display Simulation in QuarkXPress.
