File should be set-up as follows:
  • imposed press sheet file
  • all elements in 100% K (black) only
  • all type outlined
  • Sheetwise printing of images is required.
  • Maximum sheet size: 28 x 40
  • Minimum sheet size: 12-1/2 x 19
  • Gripper margin: 3/4" (minimum to scratch-off area)
  • Tail, guide, and wild : 1/2" (minimum to scratch-off area)
  • Please mark clearly guide and gripper, use operator side guide if possible.
  • Trapping screen printed scratch off image to an offset printed graphic image will not work. +- a 1/16" is realistic.
  • Full coated sheet of paper, gloss is best, dull will work.
  • NO Matte, or any Uncoated sheets. (Finch fine is uncoated)
  • 80# book weight minimum.
  • A #3 or better grade is recommended.
  • Conventional printing inks should be used in conjunction with a barrier (rub resistant) varnish.
  • Use of wax free ink and varnish is not recommended.
  • The varnish is best if applied with a "dry plate" method. Spot varnish is acceptable if applied properly. Aqueous coating is OK if applied properly over a good (#2 or better) coated paper.
  • Use a minimum of offset spray powder, scratch off will bond to the spray powder.
  • Under the play area (scratch off) use as many ink layers as the graphics will allow.
If security is a factor:
  • Use heavier paper that has more fiber content i.e. 8pt or 10pt C1S.
  • Screen down the play image.
  • Print a security pattern on the back of the sheet behind the play area.
  • Use graphics under the play area that visually disrupt the play area image.
  • Offset overprinting of scratch off is not recommended, if necessary for security reasons, please discuss with SLC prior to quoting job.
  • Please provide the following information. Sheet size, Weight of paper, Square inches of coverage per sheet, Color of scratch off (silver, gold, special), Quantity of sheets.
