    Abstract: Techniques are described for printing on front and back surfaces of security document substrates in a manner that conserves use of print ribbon, thereby extending the life of the print ribbon. In general, the printer controller knows the content, as well as locations and colors, of what has been printed on the front or first surface of the security document substrate. The printer control also knows the content, as well as locations and colors, of what is to be printed on the back or second surface of the security document substrate. When the back surface of the substrate is to be printed, the printer controller determines, for a particular color, whether any of the printing on the back surface would overlap with the printing on the front surface. For locations where there would be no overlap, the printer can reuse the section of print ribbon that was used to print on the front surface to print on the back surface.

    Abstract: A mounting of a ribbon supply on a re-useable cartridge is described where the mounting is designed so that the supply friction, supply and control of the ribbon supply are substantially independent of the cartridge. When the supply rolls are initially mounted on the cartridge, the supply rolls are frictionally engaged with the cartridge to reduce the tendency for the supply rolls to rotate or move prior to being loaded into the printer, which would loosen the ribbon material by unwinding, thereby reducing slack in the ribbon material. When the cartridge is loaded into a card personalization machine, features on the card personalization machine automatically reduce the frictional engagement between the supply rolls and the cartridge, permitting the supply rolls to rotate substantially freely relative to the cartridge so that the supply friction, supply and control are substantially independent of the cartridge.

    Abstract: An image to be printed on a surface of a substrate that forms, or will be used in, a personalized security document is generated. The image to be printed is then sliced, divided, separated, etc. into a plurality of separate image portions. Each of the separate image portions is then printed onto the substrate. Together, the separate printed image portions form the desired image on the substrate. Each image portion contains only a portion of any confidential or personal information. Each separate image portion is printed using separate sections of a single print ribbon. Since each image portion is printed using a different section of the print ribbon, each ribbon section contains only a portion of any confidential or personal information. This makes it difficult for someone to obtain the confidential or personal information from just a brief or casual glance at the used print ribbon.

    Abstract: A technique is described for determining pixel dropout in a printhead that has a plurality of print elements arrayed along an axis. In the technique, a dataset of integrated intensity values, in the printing direction on a substrate, of a captured image is generated and used to determine if pixel dropout has or may have occurred.

    Abstract: Methods and systems for remote, asynchronous key entry and extraction are provided. A credential device can store a first key thereon, and can store an encrypted key component. A hardware security module manages a key template including a plurality of key components. The hardware security module manages a complementary key to the first key. The key component on the credential device can be encrypted with the first key for storage on the credential device and decrypted by the complementary key at the hardware security module. Alternately, the key component can be encrypted with the complementary key and provided to the credential device for decryption at a secure system via the first key. Accordingly, a key custodian may supply or extract a key component at a hardware security module remotely and at a time convenient to that key custodian.
