摘要： A program with complete conditions for a usable mask yields a unitary mask, each try. One mask pattern is used throughout an image, but may be “tiled”. Preferably the program, for given mask position, expresses favorability of several candidate pass numbers as a “neighborhood constraint” in the form of a weight; distills the weights into one weight for each pass number; based on that, chooses a number for the position; and iterates for all positions. Many preferences are very useful, e. g. automatically balancing randomness vs. determinism, and several generalized relative notations. Another invention facet uses an input text file of mask constraints; a program reads constraints from the file, applies them, forms a mask and stores/uses it. Another reprocesses a mask for best image quality, fixing its own imperfections of first-round mask forming.

摘要： The method enables swath-type bidirectional printing without hue shift, using plural scanning multiple-inkjet printheads (holding inks of different colors respectively) and printing-medium advance orthogonal to the scan axis. Inking is calculated and implemented for each position in the grid independently. Images appear as a pixel grid of columns and rows both spaced--i.e. in both the scan and media-advance directions--more finely than 300 dpi. In one aspect of the invention, both these resolutions are the same, and equal to the nozzle spacing. At least some of the nozzles are overlapping and respectively aligned along the advance axis, to be capable of printing on adjacent rows during a single pass. In another aspect of the invention, the nozzle arrays only partially overlap, so as to use significantly fewer than the total number of nozzles in each array. As to this second aspect of the invention, in each nozzle array the method uses a number of nozzles that is fewer than the total nozzle complement by a certain number that is preferably at least fifteen, more preferably thirty, and ideally roughly sixty nozzles.

摘要： A shingle mask has width mismatched to maximum-eye-sensitivity spatial frequency at reading distance or closer, so the mask is tiled with minimal patterning. A second invention facet forms a grid of optimum width—it corresponds to maximum sensitivity only if seen from much farther than reading distance. A third facet forms a 2D mask with width 0.25 to 2 inches, better 0.375 to 1.5, ideally 0.5 to 1 (progressively further from maximum sensitivity; as further increases help little, this enables bandfree printing without very large masks). A fourth facet optimizes width in terms of distance in the image, for aesthetics, speed and economy. Another facet automatically forms a mask that time-varies nozzle-use modulation. Another prints nontext images by a multinozzle pen, modulating use; still others by plural pens each with a multinozzle array, refraining from use of certain nozzles e.g. to simulate dynamic pen staggering.

摘要： Color inkdrops form on a print medium in at least partly overlapping swaths. Apparatus holds and provides--or generates in real time--data defining a generally randomized printmask, which is applied to control working parts of an inkjet printer. Preferably the apparatus establishes an elemental pixel subgrid of rows and columns, used in determining inking patterns essentially throughout the image; and stores in the pixel subgrid a previously generated, generally randomized selection of pixel columns for printing of an inkdrop, in each subgrid pixel row--and conversely an analogous selection of pixel rows for printing a drop in each subgrid pixel column. Also preferably the generally randomized selection is subjected to location rules as to pixels above and to at least one side of each pixel. Numerous specific masks are specified as pass-number patterns, including an eight-by-eight "knight" array, two sixteen-by-five arrays, a sixteen-by-ten array, and several four-by-four arrays. Another form of the invention includes apparatus for minimizing directional and other patterns in a printed color image, and coalescence and puddling of ink. A method of creating and using a printmask includes generating, as a row-and-column array, a series of essentially randomized numbers for use in defining rows or columns, or both, of a pixel subgrid; and storing the array in a tangible medium.

摘要： An inkjet printing system uses high-resolution printheads holding different color inks to produce true 600 dpi color printing with a single pass of the printheads. By achieving a smaller drop size in the range of 25-50 picoliters for each printhead having a separate ink color (yellow, cyan, magenta, black), a full range of high-resolution color print-quality modes is possible. In an exemplary embodiment with a carriage scan speed of 25 ips, a two-pass draft mode uses a 7.5 kHz firing frequency, a four-pass normal mode uses a 4 kHz firing frequency, and an eight-pass best mode uses a 2 kHz firing frequency. In all of these print modes, each printhead can provide color inkdrop placement on every pixel row during a single pass.

摘要： Bidirectional scanning printheads discharge color-ink drops at ultrahigh resolution while scanning in each direction, to form color swaths on a print medium. The heads are at least partially aligned with respect to the longitudinal axis of the medium, so that the swaths at least partly overlap in that direction. An advance mechanism intermittently steps the print medium longitudinally, to enable displacement of successive swaths. A control system alternates (1) one full reciprocation of the heads, to discharge drops while scanning each way across the medium, with (2) each step of the advance mechanism. Preferably the heads print, while scanning each way, a respective generally fixed nonzero fraction of the total amount of each secondary color to be printed. In this way the overall appearance of each secondary is essentially consistent and partway between two appearances respectively produced by scanning two ways. This invention avoids the long-printzone drawbacks associated with full-height-staggered heads. Preferably the fractions for all the swaths are about equal, so that the consistent appearance for each secondary is essentially the average of two appearances respectively produced by scanning two ways. Various printmasks complete each swath in eight passes with four print-medium advances, or four passes and two advances, or two and one—in each case printing in every pass.

摘要： Scanning printheads form a color image as inkdrops in a pixel grid on a print medium. Pixel row spacing equals nozzle pitch. Apparatus holds and provides (or creates in real time) a printmask using location rules that prevent addressing, within each scan, immediately neighboring pixels in any horizontal, vertical or diagonal direction. The mask is applied to control the heads. In other aspects of the invention, the rules also prevent addressing, in each scan, horizontally neighboring pixels within the entire width of the mask; or vertically neighboring pixels within its entire height; or immediate neighbors in any direction across a boundary--horizontal, vertical, or either--between abutting masks. Specific masks are set forth implementing these aspects. Another form of the invention yields a two-pass mask with this pass-number pattern: ##EQU1## Another form is a mask-creating-and-using method: generate a number series to define rows/columns of a pixel grid for printing in successive head passes, test the numbers against rules to minimize ink coalescence, and accumulate the numbers as an array to define a pixel grid--all automatically. Also check performance of arrays so generated, select a preferred one, and store it in a tangible medium for later automatic recall to control a printer.
