A method of forming a digital print on a surface (2) by applying powder of dry ink (15) including colorants (7) on the surface, bonding a part of the dry ink (15) powder to the surface (2) by a digital heating print head (80) such that the digital print is formed by the bonded dry ink colorants (7) and removing non-bonded dry ink (15) from the surface (2).

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.

The present application provides an overprint orientation system. The overprint orientation system may include a first printer for printing on a substrate a first field and one or more orientation indicators within a second field, a second printer for overprinting the second field, and an orientation sensor. The orientation sensor determines whether the orientation indicators are visible.

A printing press arrangement has a plurality of processing stations for processing sheets. The plurality of processing stations are arranged one after another in a transport direction of the sheets for in-line processing of the sheets. At least one of the processing stations is configured as a non-impact printing device. A transfer device, which is arranged upstream of the active region of the non-impact printing device, is provided for transferring the sheets from a first processing station, which is arranged upstream of the non-impact printing device, to the non-impact printing device. The transfer device aligns, in each case, at least one of the axial register and the circumferential register and the diagonal register of each of the sheets in register relative to the printing position of the non-impact printing device.

A computer-implemented method and system are provided for enabling digital imaging of both secure and non-secure areas of instant lottery tickets on demand across a geographically diverse network. Instant lottery tickets produced with this system accommodate smaller volume print runs, process color, and a greater level of customization.

A device for processing substrates uses a separation system. Processed substrates can be separated into one or more waste parts and at least one blank. Improved flexibility for treating substrates is provided. The separation system comprises a transport cylinder and a stripping cylinder associated therewith. The transport cylinder has first openings and has a detachably secured packing having depressions in which perforations are formed, with at least one perforation covering at least one first opening. The stripping cylinder has a detachably secured packing having raised areas that correspond to the depressions.

A machine arrangement, that sequentially processes sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. Further processing stations are a primer application device that primes the substrates and a dryer for drying the primer applied to the substrates. The primer application device and the dryer precede the non-impact printing device, in the direction of travel of the substrates. The processing station including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged.

A press assembly has a plurality of processing stations for the processing of sheets. These processing stations are arranged in sucession in a transport direction of the sheets for inline processing of the sheets. At least one of these processing stations is a non-impact printing unit and at least one processing station downstream of the non-impact printing unit is embodied as a dryer. At least one additional processing station is embodied as a coating unit. The coating unit is configured for applying a coating in a form of a varnish to each sheet. A plurality of individually controlled, non-impact printing units are arranged along the transport path of the sheets. Each of the plurality of non-impact printing units is configured as an ink jet printer.

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.

A method of encrypting at least a portion of PostScript vector language, where the PostScript vector language includes a cleartext portion and a ciphertext portion, the method including: (a) encrypting at least a part of the PostScript cleartext portion via an encryption algorithm with a generated encryption key resulting in at least a part of the ciphertext portion and overwriting the PostScript cleartext portion with the resulting at least part of the ciphertext portion; (b) saving the encryption key in a file separate from a file containing the PostScript vector language; (c) linking both the encryption key file and the PostScript file in an image processor interpreting the PostScript vector language to display or print PostScript graphics; (d) decrypting the at least part of the ciphertext portion resulting in decrypted PostScript cleartext; and (e) executing the resulting decrypted Postscript cleartext to produce an image on a document or screen.
