Kan't Kopy paper

Kan't Kopy safety paper is a type of security paper printed with a moiré pattern in order to resist counterfeiting original documents. It has an embedded mark making copying obvious, as a side effect deterring further copying.

How it works

When photocopied or scanned, KK paper produces a repeated pattern of either the word "VOID" or the word "COPY" on the copies. The paper comes in red, blue, and green. The illusion of the VOID pattern is created by line segments intersecting at various angles.

Uses

Kan't Kopy paper is mainly used in coupons and official documents.
