摘要： A printer performs a multi-pass printing including: (a) pass process executed with Ka number of nozzles; (c1) pass process executed with Kc1 number of nozzles; (c2) pass process executed with Kc2 number of nozzles; and (b) pass process executed with Kb number of nozzles. Kc1 and Kc2 are greater than or equal to Kb and smaller than Ka. An upstream gradient of dot recording rates of (c1) pass process is greater than a gradient of (a) pass process. A downstream gradient of (c1) pass process is the same as the gradient of (a) pass process. An upstream gradient of (c2)-pass process is the same as a gradient of (b) pass process. A downstream gradient of (c2)-pass process is greater than the gradient of the (a) pass process. Kc1 is greater than Kc2.

摘要： Images are printed up to the edges of a print medium while preventing ink droplets from depositing on the platen. Ink droplets are ejected without blank space up to the edges of the medium according to print data. The print medium is supported opposite a dot-recording head. Ink droplets are ejected to a first area lying outside of an upper edge of the print medium and to a second area lying outside of a lower edge of the print medium. A length of the second area in a sub-scanning direction is greater than a length of the first area in the sub-scanning direction. In device embodiments, control of such operations is provided by a controller.

摘要： The image recording apparatus comprises: a full-line recording head in which a plurality of image-recording elements are arrayed across a length corresponding to an entire width of a printing medium; a conveyance device which conveys at least one of the recoding head and the printing medium in a direction substantially orthogonal to a width direction of the printing medium so as to move the recording head and the printing medium relatively to each other in a relative conveyance direction; and a recording control device which performs recording control so that when recording is carried out with respect to a solid area of a recorded image with a substantially uniform density, diameter of dots in the solid area recorded on the printing medium with the image-recording elements is made greater than an array pitch of the image-recording elements projected so as to be aligned in a main scanning direction substantially orthogonal to the relative conveyance direction.

摘要： A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle over (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle over (2)} and {circle over (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.

摘要： Feeding a recording medium through a printer for printing images on the recording medium by actuating a line feeding motor in predetermined stepped increments, feeding the recording medium through the printer by a line feeding device driven by the line feeding motor, printing a image on the recording medium by a print head scanning across the recording medium and ejecting ink from nozzles, the print head having j nozzles spaced at a predetermined pixel resolution that is less than a pixel resolution printed by the printer, j being an integer number, controlling the actuating step to actuate the line feed motor in stepped increments, and controlling the j nozzles utilized in printing the image. For each stepped increment of the line feed motor, the line feeding device feeds the recording medium (m×1/n) pixels of the print head pixel resolution, where m and n are integer numbers and m is greater than n. The j nozzles that print in any one scan of the print head are controlled based on the number of increments of the line feed motor. Additionally, a print driver calculates a line skip amount and a buffer offset amount, and adjusts a starting position for storing of the image data in a print buffer in a case where a first line of image data to be stored in the print buffer is white data.

摘要： An inkjet printer uses a printhead that passes repeatedly across a print medium in individual swaths. The printhead has individual nozzles that are fired repeatedly during each printhead swath to apply an ink pattern to the print medium. Before any given swath, the printer analyzes factors that might require a reduction in print density. Anticipated printhead temperature is one factor that might require a reduction in print density. The printer monitors the print density and peak printhead temperature during each printhead swath. It then uses these values to calculate, prior to each new swath, a maximum permissible print density. If a reduction in print density is required, the printer temporarily disables selected nozzles to produce a reduced-height swath rather than pausing between swaths or reducing the printhead velocity relative to the page.

摘要： Large, overlapping "mega-dots", placed on small, high resolution pixel locations, are used in high quality monochrome imaging to preserve information to the micro, or pixel, level, thus avoiding the need to use micro-sized droplets. By using multiple passes and multiple pens with different levels of gray ink, one may build a single monochrome 600 dpi (dots per inch) pixel with the composite gray of those droplets at that pixel location as well as the neighboring locations. With careful print modes and multiple passes, one can produce several levels of gray at a particular pixel location. The biggest advantage of using multipixel dots is that the sensitivity to trajectory errors is significantly reduced. For example, a dot that is 1/150.sup.th inch diameter is almost indifferent to a 1/1200.sup.th trajectory error. Even a relatively large 1/600.sup.th inch error has little impact on the large 1/150.sup.th dot (25% error). In reducing the sensitivity to trajectory errors, overall imaging errors, such as banding, can be reduced, and overall image quality enhanced. Optimally, the large dots have a diameter that is about three to five times the pixel size, providing an overlap of three to five dots, respectively.
