We offer 3 types of foil, silver, copper and gold. Each order can only have one type of foil. You can’t order a foil job with gold foil on the front and silver foil on the back.
Foil mask files are set up just like our spot UV mask files. The file can only be black and white. All black areas must be 100% black with no other colours added. Black in the areas you want the foil and white in the areas you do not want the foil. If you order a foil job with spot UV, you must provide separate mask files for the foil (foil mask) and UV (spot UV mask), in that case up to 6 files will need to be provided.
However, please keep in mind that the foil and UV can’t overlap. Also please avoid using small / fine text or fonts for foil objects. For best results, please make sure that foil coverage is less than 50% of the artwork area
Also, be aware that there may be up to 1/16″ shift on the placement of the foil. Keep this in mind if you are trying to align foil with other printed artwork on the card.
