Abstract
A method and system include digitally imaging a secure portion and a non-secure portion of scratch-off coating protected gaming documents of at least one game, the gaming documents including variable indicia, the gaming documents and the at least one game being associated with at least one overall print run, each print run including (i) a plurality of non-winning gaming documents and (ii) a plurality of winning gaming documents determined by revealing secure variable indicia according to predetermined game programming, and wherein at least the secure portion of digital imaging is hidden under the scratch-off coating. The secure portion can be encrypted into ciphertext with the non-secure portion remaining plaintext or cleartext. This enables digital imaging on demand across a local or distributed network of both secure and non-secure areas of instant lottery tickets or other documents having scratch-off coatings.
