Compact Disc Silkscreen Labeling Specifications

The silkscreen label is the information which is silk-screened directly onto the CD-ROM label. Two color labels are included in our standard price list but you can have more colors for an additional fee. If looking for four colors or more, we strongly suggest you consider offset printing instead of silkscreen. The quality is much better.

Please indicate "top" on each piece of film.

INK COLORS

Colors printed on discs may vary from paper printing colors. Please allow for (+ or -) 1/2 shade deviation tolerances.
Colors may not reproduce accurately when they are over printed.
If printing inside 47mm DIA, color may vary due to mirror band and/or clear inner hub.

HALFTONES AND 4-COLOR PROCESS SCREEN IMAGES

All film for process orders must include a film produced color proof. Examples: Chromalin, Iris, Composite Match Proof, etc. Laser printed artwork proofs are NOT acceptable.
Printing a halftone without a white base will alter the ink color.
Color separations should be done specifically for Screen Printing using ELLIPTICAL dots. Lithographic separations are not acceptable.
The separations must be angled to reduce moiré. A variety of angles can be used successfully, but the colors should be angled in the following order:
YELLOW - 7 degrees MAGENTA - 52 degrees
CYAN - 22 degrees BLACK - 82 degrees
Separation tonal ranges should be adjusted to be no less than 20% and no greater than 80%
