Someone in a forum I visit asked why he gets incorrect color when converting from Pantone to CMYK in Quark XPress. While I do not have the answer (though I have a guess or two), I do have a solution. It's not the most elegant solution, but it works.
Step 1: Create a Pantone color in Quark Xpress. For this tip, I chose Pantone 542. (See diagram at right)
If you still haven't experienced the joys of Adobe InDesign, and you frequently find yourself swearing at Quark XPress for providing you with a perfectly useless preview image of your placed Photoshop EPS file (duotone files require the use of EPS), then this is for you!
