Abstract: The disclosed embodiments include a method to compensate for defective printer nozzles. The method can include detecting a defective printer nozzle and initiating a print job including image data of the defective printer nozzle for a pixel location of an image. The image is to be printed in accordance with a print mask that maps printer nozzles to pixel locations of the image. The method can include modifying the image to print the image data in a neighboring pixel location relative to the pixel location of the image and printing the modified image.

Abstract: In a color printing environment, functions for printing color management are dissociated. An abstraction layer is also provided to facilitate setting and evaluation of all factors relating to color print and prediction.

Abstract: Compensation algorithms are applied to hide failed nozzles or, at least, reduce the objectionable effect of such nozzles in a printed image. Once a failed nozzle or under-performing nozzle is detected in a single-pass printing system, it is shut-off and the image data that was intended to be printed by this nozzle is redistributed to its neighboring nozzles. Embodiments of the invention use of a 1-D look-up table and stochastically distribute the duty cycle to each neighboring nozzle. In this way, failed nozzles are effectively hidden in the final print.

Abstract: The disclosed embodiments include a method to compensate for defective printer nozzles included in printer nozzles used to print an image on a medium. The method includes detecting defective printer nozzles, and initiating a print job in a print mode. The print job can include image data used to print the image on the medium in accordance with a print mask that maps the printer nozzles to pixel locations of the image. The method further includes modifying the print mask or the image data to print using the image data with printer nozzles that may be complementary to the defective printer nozzles, and printing the image on the medium in accordance with the print mode and the modified print mask or the modified image data.

Abstract: A system and methods for printing and curing ink deposited on a substrate using a first light source and a second light source. In various embodiments, the first light source emits one or more wavelengths of electromagnetic radiation subtype C (UVC), and the second light source emits one or more wavelengths of electromagnetic radiation subtype A (UVA), subtype B (UVB), subtype V (UVV), or a combination thereof. The substrate is configured such that any ink deposited on the substrate by a printer head is predominantly exposed to the first light source prior to the second light source.

Abstract: A fluid ejection device and a printhead including one or more such fluid ejection devices are provided. The fluid ejection device includes a substrate having a first nozzle array and a second nozzle array, each array having a plurality of nozzles and being arranged along a first direction, the first nozzle array being arranged spaced apart in a second direction from the second nozzle array. A first fluid delivery pathway is in fluid communication with the first nozzle array, and a second fluid delivery pathway is in fluid communication with the second nozzle array. Nozzles of the first nozzle array have a first opening area and are arranged along the first nozzle array at a pitch P. Nozzles of the second nozzle array have a second opening area, the second opening area being less than the first opening area. At least one nozzle of the second array is arranged offset in the first direction from at least one nozzle of the first array by a distance which is less than pitch P.

Abstract: A method of selecting inkjet nozzle banks for assembly into an inkjet printhead. The printhead when assembled includes at least two nozzle banks and is operative for printing one particular color ink or other liquid and each nozzle bank includes plural nozzles. The printhead is operational in a printer to print raster rows so that at least one raster row is printed using ink drops deposited at respective different pixel locations on the raster row by respective different nozzles on each of the at least two nozzle banks.

Abstract: A method is provided for optimizing a printer for driver settings and color profile in order to optimally print an image on a selected media. Data is stored in an index file for various combinations of printers, printer drivers, printer media and color profiles. The printer driver that is currently used on the user's machine for the selected printer is determined and the printer media selected for the printer is identified, e.g., by a simple query of the user. One set of steps involves choosing an appropriate stored color profile for the selected printer-media combination, and applying the chosen color profile to the image data, thereby generating transformed image data. Another set of steps involves retrieving printer settings for the selected printer-media combination and modifying the settings of the driver in use for the selected media.

Abstract: A method is provided for reducing image artifacts in printers that employ two or more printhead nozzle banks that must be aligned and registered with respect to each other either through adjustment of orientation and/or position of one nozzle bank relative to another or through selective control of actuation. In the method, discrete dots are printed by the nozzle banks upon a target receiver medium. Examination of the receiver medium or a reproduction thereof is made by a scanner and information regarding location of the dots is generated. From information regarding location of the dots a determination is made of error placement of the dots from ideal locations. Alignment of the nozzle banks are made in accordance with any errors determined in placement.
