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: 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: 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.
