Technical Tips

Here are some of our top foil printing tips:

  • Foiling areas must be wax free with a surface tension of 38 dynes per square cm or above, we might sometimes be able to work with a lower dyne level
  • Allow at least 25mm from grip / lay edge to the area to be foiled
  • Up to SRA3 put the grip edge should be at the top of the sheet and lay to the right edge
  • Above SRA3 the lay edge to be to the left
  • Always consider the choice of paper or board before offering foil printing as a finish
  • Do not reverse out foil blocking areas to assist with registration
  • Larger text size works better than smaller text and typefaces generally appear bolder once foiled. Be aware of this during the design phase
  • If foiling two areas; a solid area and a fine area, expect to make two machine passes
  • When preparing artwork for embossing always remember to accommodate for the bevel
  • It is not yet possible to foil onto spot UV varnish or certain inks and other varnishes
  • Always consider what will be on the reverse side of the hologram as it could detract from the hologram effect
  • For the best hologram effects avoid square corners if possible
  • If sealing use an aqueous rather than solvent based sealant
