Abstract: According to one example, there is provided a method of processing an image. The method comprises obtaining image data representing an image to be printed, determining, from the image data, pixel locations on a substrate where ink is intended to be deposited and pixel locations where no ink is intended to be deposited, and modifying the image data to define varnish to be deposited at at least some of those substrate pixel locations determined as where no ink is intended to be deposited.

Abstract: Certain examples of printers and methods of printing may involve determining colorant amounts of image regions within a print image.

Abstract: A method performed by a printing system is described herein. A request is provided to a user to enter data related to print quality of a mark or marks printed on a portion of a background region. The background region includes an area or areas treated with a fixer fluid applied by a printhead. A user input is received associated to the request. A misalignment of the printhead is estimated in accordance with the user input. A printing system and a tangible machine readable storage medium are also described herein.

Abstract: A method of printing an image with an inkjet printer system, said system comprising a printhead arranged to print swaths of image content parallel to a first axis on a print medium, said swaths having a width in a second axis substantially perpendicular to said first axis, said method comprising the steps of: determining the length of said image in said second axis; and, resizing said image such that said resized length of said image in said second axis is substantially an integer multiple of said swath width.

Abstract: To decrease the total time required for feeding an inkjet printing medium to print an image, swath heights are reduced to values that depend on overall image height. A processor in the printer works out the swath height that just corresponds to an integral number of print-medium advances, over the total height of the image; and then prints the image using this swath height. This strategy optimizes throughput by minimizing the time occupied in advancing the print medium and in adjusting the print-medium position.

Abstract: A printhead makes passes over a printing medium, each pass forming a swath of marks on the medium. In one aspect of the invention, between passes the medium steps by a nonzero distance that varies from step to step. In another aspect, swath edges are spaced away (ideally well away) from each other. In yet another aspect a printer has a reciprocating carriage—to carry a printhead for forming, in each certain multiple of a half-reciprocation, a swath of marks on the medium. Each head includes multiple printing elements, a number of combinations of groups of which are used to print each region of each swath; the invention increases the number of combinations used to print each region. In still another aspect, the step distance is random or randomized. Ideally these aspects are all used together. Preferably (1) step distance varies at every step—e.g.

Abstract: One invention aspect forms a mask and matrix of corresponding backups for values in the mask, checks when a mask value is not working, and replaces only that value with only a matching matrix entry. A second matrix of further backups is best formed. Another aspect forms a mask as a matrix of stacks of matching entries for mask positions; selects an entry for each position from the matching matrix stack; and prints using the selected entry at each position. Another aspect forms a mask as a matrix of stacks of matching entries for mask positions, and rotates each stack to select an entry for each position. Another aspect forms a mask and a matrix of stacks of backups; finds nonworking mask values and replaces such values with backups from a matching stack. Another aspect forms a seminal mask, tiles it to make a larger one with related properties, and injects noise to disrupt tiling-caused regularity and form a less-regular mask.
