摘要： A method for reducing banding artifacts for bi-directional multi-pass printing on an inkjet printer utilizing a printhead with a plurality of ink nozzles includes defining different print masks to be used for leftward and rightward printing passes such that both the order of ink laydown and the timing between ink laydown on different passes are each substantially constant for a given horizontal position within the image, independent of the vertical position within the image; and printing an input image on the inkjet printer with the defined print masks using a bi-directional multi-pass print mode.

摘要： A method of determining and applying a protective ink amount to be printed in addition to a plurality of colored ink amounts to make colored pixels in an image including determining a first protective ink amount responsive to the colored ink amounts, determining multitoned colored ink amounts using a multitone processor responsive to the colored ink amounts, and determining a second protective ink amount responsive to the multitoned colored ink amounts. The method also includes determining the protective ink amount responsive to the first protective ink amount and the second protective ink amount to provide adequate durability for the image, and applying using an inkjet printer the colored ink amounts and the protective ink amount to make the colored image pixels.

摘要： An arrangment is disclosed for reducing edge artifacts produced when printing a digital image on a digital printer, which printer is capable of producing multiple output levels, said digital image being represented as a rectangular array of pixels. In this arrangement, the following steps are accomplished by: computing difference signals between a center pixel value and pixel values of a set of one or more neighboring pixels; determining a pixel correction value responsive to the computed difference signals; and computing a new center pixel value by modifying the center pixel value using the pixel correction value.

摘要： A method for printing images on an inkjet printer having grayscale print and color print modes, comprising performing an inspection process to inspect lines of image data in an inspection region downstream from a current swath of image data to determine a print mode for a future swath of image data. The inspection process includes inspecting the lines of image data in the inspection region according to a predetermined inspection sequence, determining whether an inspected line contains any pixels to be printed with color ink, and if so terminating the inspection process and designating that the future swath is to be printed with the color print mode; otherwise, if none of the lines are found to contain any pixels to be printed with color ink, designating the future swath to be printed with the grayscale print mode.

摘要： A method for reducing banding artifacts in a printed image, including irregularly advancing a media that will be printed upon while employing an entire single mask for marking elements of a printhead; and calculating a difference between an irregular advance amount of the media versus a nominal advance amount of the media. Finally, the single mask is nonuniformly circulated by the difference calculated in order to compensate for the media being irregularly advanced.
