Why does my proof look black on my Mac?

The default program for opening PDF files on most Mac computers is called Preview. Unfortunately, this program can distort some colors, particularly spot colors. If you are a Mac user and have downloaded a PDF of your proof, please do not view the file using Preview, it will cause the artwork to look black or strangely colored. Please always view proofs in Adobe Reader. Reader is available for FREE  here: http://get.adobe.com/reader/.
