Film Requirements for On Disc Printing
On Disc Printing Film Requirements
For the highest quality on disc printing reproduction our preference is client supplied electronic files and we will output the films. However, if you prefer to supply films, please follow these specifications:
• A film positive, right reading, emulsion side up, with a minimum resolution of 2400 dpi. Film thickness should be 4mil (.10mm).
• Log density of 3.5 for flat printing, 4.0 for halftone and line art. Clarity in film base should have a log density between 0.0 and 0.2 and be optically clear. The film should also be free from contamination, scratches and creases.
• Minimum film size 8" x 8".
• CD printable areas are:
a. 45mm-118mm; Standard circle.
b. 36mm-118mm; Standard circle including mirror band.
c. 20mm-118mm; Edge to edge and must include a white knockout ring between 32mm and 36mm diameters.
• If using a solid white base color, "flood", a film positive, emulsion side up, with a .5pt choke on all edges may be supplied.
•However, for standard flood areas shown on "Compact Disc Printing Specifications" sheet: CD printable areas A, B, or C, films are not required. Client must indicate preferred flood to match artwork. Client will not be charged for standard (A,B,C) flood films.
• The film for the base color must match the graphics and must be specified on the order "Print white base color".
• Please refer to CD Printing Specifications Template.
• Recommended line screen is 85lpi with
a maximum of 100lpi.
• Dot shape must be elliptical and within the 20-80% dot range.
• Only linear gradations may be used. Radial gradations will produce a moiré.
• Templates are available for layout purposes.
• Shipping: each film to be separately slip-sheeted, secured, and thoroughly protected to prevent scratching, puncturing or folding.
Type Size/Line Width
Minimum regular type size is 4pt (.056"/1.40mm). Minimum serif width is 0.5pt (.007"/0.175mm).
• Minimum character line width is 0.5pt (.007"/0.175 mm).
• Minimum reverse type size is 5pt (.07"/1.75mm).
• Minimum reverse character line width is 0.75pt (.01"/.265mm).
• Bold face type preferred. For best results, use a Helvetica bold-type font.

• Dot shape: Elliptical.
• Ink density scanner setting (GCR) from 250280%, depending on artwork (transparency).
• Screen angle for one color halftones:45ƒ (Black).
• Color separations should be produced exclusively for screen printing, using elliptical dots. Lithographic separations cannot be used.
• Separation tonal ranges should be adjusted to be no less than 20% and no greater than 80%.
• The separations must be angled to avoid a moiré pattern.
• Halftones should be angled in this order:
◦ First halftone in sequence: 45ƒ
◦ Second halftone in sequence: 75ƒ
◦ Third halftone in sequence: 105ƒ
Ink Colors
• We recommend that colors do not overprint with the exception of black, which will print on top of other colors.
