I'm having some work printed, and without a Pantone booklet to accurately select the Pantone's I'm after, I called the printer today to ask for their suggestions. Their suggestions seem pretty good just eyeballling them onscreen, however in checking the CMYK values of my Pantones with the CMYK's of the equivalent Pantone's that the printer suggested, there's a good few differences.
Pantone 476 Coated per the printer is CMYK 57/80/100/45
Per Illustrator 9 on my computer, 476 breaks down as 79/83/100/0
Any issues with this?
