    摘要： 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.

    摘要： 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.

    摘要： 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.
