Discs are printed with a different process than the rest of the packaging. Booklets, digipaks, and jackets are printed with process (CMYK) inks, using a high-quality process called offset printing. Discs are printed with spot colors, and are silkscreened. There are a couple of key differences to keep in mind: • The tonal range that we can hold while silkscreening the discs is 15-85%. Tones lighter than 15% may blow out to zero, and those darker than 85% may fill in completely. As a result, we do not recommend using very dark or very light photos on the disc. • High-contrast images work best. Subtle changes in tone can be lost in the silkscreening process. • Gradients or blends do not print well, and can look uneven or blotchy. We strongly recommend avoiding gradients or blends on the disc.
