I'm a new designer who is trying to solve issues of color variations when I create a PDF file from Illustrator CS5. Can anyone tell me what I need to do to ensure that the colors match from application to application? Do I need to select certain settings for RGB, CYMK, or other color libraries (i.e., Pantone)? Thanks for the help!
If you are creating your PDF using Save As > PDF or Print > PDF; your selections in Illustrator's Color Settings should go with the file. However, it could also be the settings you choose when you create the PDF. I use Distiller where I can use the same settings from Illustrator and have them embedded in the PDF when distilled. The key being that settings match when you create the PDF.
