What is a black mask file and when do I need it for scratch-off printing?

A black mask file is a separate file that tells the production team exactly where the scratch-off coating should be applied on your printed piece. You need it any time you order scratch-off printing, because the mask defines the shape and position of the removable layer.

• What it shows: the size, shape, and location of each scratch-off area, drawn in solid black.
• What it does not include: the hidden code or message underneath, which belongs in your main design, not the mask.
• Placement freedom: the scratch-off area can sit anywhere on the piece as long as the mask marks it clearly.
