摘要:
Target patterns capable of being printed on a medium are determined. The target patterns are adapted to provide quality assurance (QA) verification of at least a reading device capable of reading the target patterns printed on the medium. The target patterns are also adapted to provide security authentication of an entity associated with printing of the target patterns on the medium. The target patterns are then printed on the medium.

A method and system for determining void pantograph settings is presented. The method includes obtaining electronic images of one or more predefined test sheets having a plurality of void pantograph settings, modeling one or more regions of the electronic images, predicting the sensitivity of the plurality of void pantograph settings to a print/scan process, the predicting being based at least in part on the one or modeled regions, and identifying characteristics for a candidate void pantograph setting using the prediction step results. The system includes a controller, a modeling unit, a measuring unit and a prediction unit configured to perform a method in accordance with an embodiment of the invention. A computer readable medium containing executable instructions is also described.

A method and system for generating a document having a void pantograph highlight pattern is presented. The method includes computing a score for a void pantograph highlight pattern layer in relation to a document formatted content layer, incrementing a relative position of the void pantograph highlight pattern layer and the document formatted content layer, repeating the computing and the incrementing steps to obtain a plurality of scores at a plurality of relative positions, evaluating the plurality of scores to determine an optimal alignment, and printing the document using variable-data printing techniques, wherein the printed document has a multi-layer architecture including the document formatted content layer and the void pantograph highlight pattern layer. The system includes a control processor, a score computation unit and an evaluation unit. The control processor provides a printer with data containing a multi-layer architecture document having a document formatted content and a void pantograph highlight pattern.
摘要:
A multiple resolution readable color array printed for labeling or displayed electronically achieves readable data at multiple optical resolutions. The array has a hierarchy of cells, where cells at a lower level of resolution include spatially adjacent smaller cells at a higher level of resolution. Colors are encoded in redundant cells within the hierarchy so that overall color assigned to a lower resolution cell depends on the colors encoded in the included data cells at a higher resolution.

Various multi-modal security deterrents (10) and methods of generating the same are disclosed herein. One embodiment of the deterrent (10) includes first and second sets (12, 16) of 180° phase-insensitive glyphs (14). One or more of the glyphs (14, Gi8o) in the second set (16) are rotated 180° from corresponding glyphs (14, G0) in the first set (12) such that the sets (12, 16) of glyphs (14) have an identical signature pollable by a suitable transmitter/receiver operating in the GHz-THz range and such that the sets (12, 16) of glyphs (14) have a different visual appearance. Data is encoded in one or more of the glyphs (140 of the first set (12) and one or more of the glyphs (14) of the second set (16) such that each set encodes a different message.
摘要:
A reading device reads ambiguous target elements of an authentication target printed on a medium. Each ambiguous target element has a number of different manners by which the ambiguous target element can be interpreted by the reading device. The authentication target as read by the reading device is compared against an authentication signature of the reading device. The authentication signature specifies for each ambiguous target element an expected manner by which the reading device interprets the ambiguous target element as one of the different manners by which the ambiguous target element can be interpreted. Where the authentication target as read by the reading device matches the authentication signature of the reading device, the reading device is signaled as having passed authentication.
