摘要： A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as the first gray level and an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level, computing a change in pixel error by toggling with all the possible output states and swapping with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met. Once the end criteria is met, the updated HTI is saved as a final halftone screen for that gray level and copied as the initial HTI for the next gray level along with CTI pixel values updated to the next gray level till the final gray value is reached.

摘要： Embodiments described herein provide variable heat control for a printer. One system includes a dryer operable to dry ink applied to a print medium. The system also includes a controller communicatively coupled to the dryer and operable to filter a bitmap to provide variable heat control from the dryer to the applied ink according to the bitmap to attach the ink to the print medium. The print medium may be a continuous form print medium. In this regard, the controller maybe operable to determine a speed at which the continuous form print medium is moving, to generate a heat control signal operable to provide the variable heat control, and to delay transmission of the heat control signal based on the determined speed of the continuous form print medium until the ink applied to the continuous form print medium is within range of the dryer.

摘要： Systems and methods are provided for altering the content of a PDF print job. The printing system includes a memory, an interface, and a markup engine. The memory includes criteria for identifying Portable Document Format (PDF) content stored in print jobs, and also includes a mark-up instruction for altering printable PDF content stored in print jobs, where the mark-up instruction references one or more of the criteria. The interface is operable to receive a PDF print job for processing. The markup engine is operable to access the mark-up instruction, to review the PDF print job to identify multiple segments of the print job that each include PDF content that matches the one or more criteria referenced by the mark-up instruction, and to alter the identified segments based on the mark-up instruction.

摘要： The systems and methods presented herein provide for calibrating a print engine of a printing system. The printing system prints image data on a print medium and scans the printed image data. Color values of the scanned image data are then measured and various tints of color values and their transition locations are identified. A calibration module estimates the original optical densities of the identified color value tints and generates a target optical density for each of the identified color value tints using the estimated original optical densities to determine print irregularities in the color values of the scanned image data. The calibration module then generates a halftone screen based on the mean optical densities and applies the generated halftone screen to the print engine to calibrate the print engine.

摘要： Systems and methods of reusing binary bitmaps for images appearing multiple times in a print job. In one embodiment, a system stores a binary bitmap for an image that appears in a print job. The system determines an offset of the binary bitmap into a sheetside, and calculates position values for the binary bitmap based on the offset of the binary bitmap. The system identifies a next appearance of the image in the print job, determines an offset of the image into a sheetside for the next appearance, and calculates position values for the next appearance of the image based on the offset of the image. The system determines if the position values for the image correspond with the position values for the binary bitmap, and verifies that the binary bitmap is reusable for the next appearance of the image if the position values correspond.

摘要： Systems and methods for a dryer unit of a printer. In one embodiment, a dryer unit includes a light source having a plurality of lamps. The dryer unit further includes a controller that associates a target output power with each of the lamps of the light source. When in operation, the controller determines a speed of a printable medium that passes through the dryer unit. The controller is able to vary an intensity of light generated by the light source based on the speed of the printable medium by varying which of the lamps of the light source are energized to their target output power.
