How are PMS colors separated on the CD/DVD face?
Instead of utilizing the CMYK process (the standard for booklet and tray card printing), most CD/DVD faces are printed using PMS spot colors. Each spot color constitutes its own piece of film, so if a job contains 3 colors, the image setter will output 3 plates that correspond to the appropriate PMS colors. If a job requires a full color image (like a photograph), the file will be separated as CMYK and will be silk-screened on the face as a 5-color image (CMYK + White Background) or can be screened directly on the CD/DVD silver.
