Abstract: Methods and systems for creating a security mark for a document. A first generation print can be rendered based on one or more patterns (e.g., pantograph pattern) for a security mark. Post-copy results of the pattern(s) can be then rendered. The first generation print and the post-copy results of the pattern(s) can be calibrated, and the output of the calibration of the first generation print and the post-copy results are then applicable for optimizing the design of the security mark for a print condition. Optimization of the design of the security mark for the print condition can be implemented by applying the output of the calibrating of the first generation print and the post-copy results for the print condition. The first generation prints and post-copy results of pantograph pattern samples can be calibrated to drastically reduce the time and labor involved in optimizing void pantograph designs for a particular print condition.

Abstract: A printing system comprises one or more printheads arranged to eject ink to a deposition region. Print media are held by vacuum suction against a movable support surface, which transports the print media though the deposition region. The vacuum suction is communicated from a vacuum source to the movable support surface via a vacuum plenum. An airflow control system comprises one or more dampers arranged in the vacuum plenum to control airflow between the vacuum source and the movable support surface. The dampers have an adjustable impedance to airflow through the damper. The airflow control system is configured to adjust the impedance of the damper based on a detected condition of the printing system. A detected condition of the printing system may include, for example, a sensed pressure in the vacuum plenum.

Abstract: Methods and systems for rendering a transparent pantograph pattern. A background path and a foreground path for a pantograph pattern can be determined. An intersection internal to the background path and external to foreground path that is to be marked can be defined. Areas to be masked can be defined with respect to the pantograph pattern. The pantograph pattern can be then rendered as a transparent vector pattern pantograph by writing a background based on the background path and a foreground based on the foreground path and the areas defined as masked.

Abstract: A method for rendering a correlation mark on a recording medium can involve encoding a pattern based on a correlation effect color based on a color recipe that includes a high density of one primary color and a mid-to-low density of at least one other primary color, and adjusting the pattern to ensure that the encoding is lost in a resulting rendering of a correlation mark embedded with the pattern. The pattern imposed on the correlation mark is not readily visible in an original without a decoding key. The correlation mark can include a frequency that is sufficiently high so that a copy of the correlation mark may not reproduce with the pattern.

Abstract: What is disclosed is an object holder for retaining an object in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a shuttle mount configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object. A plurality of threads, at least partially comprising a flexible synthetic elastomer, are connected to the shuttle mount. The threads are joined together to form an elastic netting which can be manually expanded around the object to retain the object to the shuttle mount while the object is being printed in the direct-to-object print system.
