Pantone assigns equivalent CMYK numbers to each of their spot color chips. And writes the CMYK numbers by their PMS spot color chip.
AI conversion within AI's dialogue box, not even close, when Adobe assigns the CMYK to a PMS.
Test it, so you see how far off this is:
PMS book has CMYK at C:0.0, M:6.0, Y:15.0, K:6.0
plenty more where that came from...
Yet Adobe offers their conversion function as a reliable tool? What is the fix for this?
Pantone assigns equivalent CMYK numbers to each of their spot color chips.
No, Pantone recommends CMYK approximations for each of their spot color chips. There's nothing stopping you from using whatever approximation you consider a better match.
would help if you indicated what pantone number you are using...
And where, exactly, you are seeing the gross missmatch you are raving about. On your monitor? Between your monitor and a Pantone swatch book? Between your monitor and a CMYK print? Between a Pantone swatch book and your CMYK print?
And WHAT VERSION of Illustrator you are using.
And what color mode your file is.
And what Color Settings you are using.
I think the post is referring to CS6's LAB color values in Illustrator, but this is just a guess. I do know that Illustrator, depending on what version you are using, has Pantone Bridge PC ( 12C, 7M, 51Y, and 22K ( my CS3 reference ), and Solid C ( 10C, 0M, 49Y, 28K which equals their reference book circa 2000 which is an older book unfortunately ). Pantone, from time to time, will reformulate some of their colors which may or may not have happened for you to get 8.5C, 0M, 47Y, and 27.5K which is no more than 2% off, nothing to lose sleep over ( 10C, 0M, 49Y, 28K vs. 8.5C, 0M, 47Y, and 27.5K ).
Thanks John, here's what I'm getting on PMS 5777C:
CS6, Swatch Libraries > Color Books > Pantone & Solid Coated with conversion in that dialog box to CMYK: 0C, 31.76M, 100Y, 0K
CS6, Swatch Libraries > Color Books > Pantone & Color Bridge Coated with conversion in that dialog box to CMYK: 26C, 9M, 56Y, 20K
Your PMS book: Solid C ( 10C, 0M, 49Y, 28K
My PMS book, not a big deal off to your PMS book: Solid C 8.5C, 0.0M, 47.0Y, 27.5K
