Abstract: A method for creating a metadata field in a template, which includes receiving a template selection, receiving a selection of a new metadata field, receiving properties of a metadata field to be added to the template, storing the properties of the metadata field, and downloading the metadata field to a scanning device in response to a signal from the scanning device.

Abstract: An image transfer mechanism includes a pressure element and a lever system. The lever system has a load attachment point with a range of position that depends on the thickness of a print medium positioned between the imaging element and the pressure element. A load mechanism includes a load connector with a distal end attached to the lever system load attachment point so that displacement of the lever system attachment point causes longitudinal movement of the load connector. The load mechanism applies a load that is substantially constant throughout the range of position of the lever system load attachment point. The load mechanism includes a spring and a crank attached to the spring and to the proximal end of the load connector. The crank is configured so that a change in the spring force produces a lesser change in the load force at the distal end of the load connector.

Abstract: As provided herein, there are supplied teachings to systems and methods for resizing a digital uniform rosette halftone image composed of multiple colorant separations, by using uniform rosette halftone tile parameters. One approach entails receiving into a digital imaging system, a digital uniform rosette halftone image and a desired resizing factor for that digital uniform rosette halftone image. Subsequently the system will define uniform rosette cells within the color uniform rosette digital halftone image. From the defined uniform rosette cells, a number of uniform rosette halftone tile seams are determined for manipulation. The orientation of the number of uniform rosette halftone tile seams is dictated by the received desired resizing factor. An energy map of the digital uniform rosette halftone image is determined according to an energy metric derived from the multiple colorant separations.

Abstract: Disclosed are systems and methods directed to digital watermarks, and more particularly, the generation of invisible correlation-based digital watermarks embedded in halftone images.
Abstract: Writing a decompressed bit-map cell in accordance with a pixel count and a fill order pattern based on half-tone threshold values of a half-toned bit-map compression cell that was used to determine the pixel count.
Abstract: A method adjusts operation of a printer in accordance with an analysis of image content used to generate printed images. The method includes measuring image content of a first print image, comparing the measured image content to a predetermined threshold, and altering a print process parameter to adjust operation of a printer component in response to the measured image content exceeding the threshold.

Abstract: A method of feeding solid ink sticks to a melting device in a phase change ink imaging device enables the solid ink sticks to move through the ink delivery system without buckling or being diverted from the feed path. The ink sticks fed to the ink delivery system have first and second contoured ends that complement the feed path to resist buckling due to feed forces and the bosses of one contoured end nest in the boss recesses of another contoured end of an adjacent ink stick to resist the effects of the feed forces as well.
Abstract: As provided herein, there are supplied teachings to systems and methods for resizing a halftone image using halftone tile parameters. One approach entails receiving into a digital imaging system, a digital halftone image and a desired resizing factor for that digital halftone image. The system will then define cells within the digital halftone image and determine from those cells, a number of halftone tile seams to suitable for manipulation. The orientation of these halftone tile seams is dictated by the received desired resizing factor. The seam energy of these halftone tile seams is then determined according to an energy metric so as to provide indication of a number of low energy determined halftone tile seams. The number of low energy seams identified is sufficient to achieve the desired resizing factor. A resizing of the halftone image is then performing by iteratively deleting the low energy determined halftone tile seams within the halftone image.
Abstract: A method facilitates insertion of a segmented ink stick into an ink feed system of a phase change ink jet printer. The method includes bending of a flexible strand between ink stick segments during insertion of the ink stick segments and then straightening the flexible strand to orient the ink stick segments in the ink feed system.

Abstract: Methods and systems are provided to increase or optimize the illumination used with a sensor to measure printed ink colors on a substrate at high speed (up to 3 m/s) and high resolution. By modifying the number of light sources, their wavelengths and/or their relative intensities, the optical contrast can be increased or optimized to yield a higher signal-to-noise ratio and improved accuracy for the measurement of multiple colors. In one implementation, multiple LEDs with selected output peak wavelength may be used to achieve higher contrast imaging for each color.
