John, matching Pantone colors on-screen to a swatch book probably isn't
going to happen. Two things are working against them:
* You need to match/view these colors in Lab color (I'm assuming we're
talking about Pantone Solid Coated and not Pantone process builds).
Illustrator only supports CMYK or RGB color modes. Whatever you choose,
you'll be getting a simulation in either RGB or CMYK which won't be
accurate to the swatch book.
* There's a good chance that their displays won't have a large enough
color gamut to display a good portion of the Pantone colors anyway.
Regards,
Terry

Greetings all,
I have a client with whom I've been working recently. They're moving
from a non-color managed environment to one that is, at least from
their point of view.
They are a mixture of machines, but the designers use G5's with
Mitsubishi 2060 monitors. I bought them a Gretag i1 display and
downloaded EyeOne Match 3 for them. We've calibrated to a 2.2 gamma,
and a 5000K white point at 100 cd/m^2. When I was bringing the RGB
controls in alignment, I'd get them close, but they would sort of
"bounce" together, apart, together, etc. So I figured that at least
they should "average" out in alignment. The calibration procedure was
straightforward, and went off as it should.
The designers primarily use Illustrator as their layout tool. They
also rely heavily on the Pantone color chart for specifying colors.
We've set the Color Settings as US Prepress defaults. When they open a
new document and select a Pantone color from the Pantone swatches in
Illustrator, after first selecting the color from the Pantone printed
swatch book, the color on screen does not match the printed chip. The
reds are dull, the yellows are not matching, and the purples look
blue. I can understand that their might be a subtle difference,
however the differences are quite dramatic. So when we print the
colors on screen to the Epson 1280, they match the screen. I created a
profile for the printer, so this was expected. I've suggested that
they select a color on screen which more closely matches the printed
chip, and simply rename it to the color they want it to be, as it's
eventually to be printed as a spot color anyhow. This affects the
overprinting values as they specify colors based on this too. So it's
not a perfect solution.
Colors picked on screen, mixed colors, and images in Photoshop all act
as they're supposed to. Since they don't use any other ink sets (Toyo,
etc.) I can't verify whether those are off as well.
What was not expected was that the Pantone swatchbook would be so
innaccurate. Is there something I've overlooked? Is this a "can't get
there from here" situation?
