It all depends on what you're trying to do. I've produced packaging for
our Dolci Frutta, a hard chocolate shell for dipping strawberries, for
years printing with cyan, PMS485 red, proc yellow, and PMS497 brown.
When the image is all yellows, oranges, reds, and chocolate brown, it
made no sense to use black, or to try to build the logo-red and small red
type by registering process red and yellow. Normally I would have run
this job as a six-color, using CMYK, and a line red for the logos & type,
and a our SACO logo PMS286 blue. Even then, the small text would have
been in unimaginative black.
With the cRyB + 286 combination, I save a plate, get much richer reds in
the fruit, and can run the text in a more appropriate brown. The 497 may
not make a huge difference in the chocolate, but having the 485 for the
Dolci Frutta logo and other copy sure helps. For this job there was no
downside.
To generate the cRyB profile, I had my engraver make a Dupont Waterproof
of the target matching the special colors, since it would be next to
impossible to get a printer to run the target with odd inks on press. I
used PrintOpen 3.0.1.
However, when we came out with a white chocolate Dolci Frutta last year -
a design that had a light blue gradation behind the fruit instead of the
chocolate package's red one - I was surprised at the separations that
resulted from using the cRyB profile (I assemble the images in A98 RGB,
and then separate when finished). Everything on the label was exactly
right, except there was no light blue gradation. All this gorgeous fruit
was floating on a field of gray. It took a bit before the "you can't get
there from here" light bulb lit up. In the end, for this package, I had
to knock-out the blue and put the background color on its own plate,
matching the blue I expected to build with a PMS equivalent. But even
then, it was still a better job than if I had stuck with CMYK.
I put together some examples for Marcelo, who asked the original
question, and if anyone else would care to see them, just let me know and
I'll send them off-list. The files are a little more than a meg when
stuffed.
