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： This invention provides an image processing apparatus capable of outputting a color image by reducing the information amount of each color component of the image by a method suited to the color component without deteriorating the quality of the image, and an image printing apparatus capable of printing an image without deteriorating the quality of the image, on the basis of received image data. Of color image data to be transmitted to the image printing apparatus (which uses, e.g., six colors Y, M, C, Bk, LC, and LM), the image processing apparatus quantizes colors (LC and LM) whose tone quality is important by a large number of gray levels (e.g., nine values), and does not compress these colors. The image processing apparatus quantizes colors (Y, M, C, and Bk) whose tone quality is not important by the number of gray levels (e.g., five values) by which the compression efficiency is improved, and then compresses these colors, thereby reducing the transmission data amount. The image printing apparatus prints the image of received image data by directly using uncompressed data and expanding compressed data.

摘要： A color ink-jet head, having plural arrays of nozzles side by side in a main scan direction corresponding to different color inks, is moved to scan reciprocally. In a multi-pass recording for divided recording on an area by scanning at plural times with the head, an ink firstly landed on recording of the area determines a prioritized color influential on the color tone. Moreover, a printing medium is largely covered by the recording of first two passes. A harmful influence on a whole image by the color irregularity can reduced by suppressing the color irregularity in the two passes, therefore, the data recording ratio of the first pass to the area is set smaller than that of the second pass and thereafter. Further, for such the control, a pseudo periodical masking data arranging record prohibiting pixels and record permitting pixels in a visually agreeable state is introduced.

摘要： In an apparatus for performing printing using a color ink-jet head having a plurality of ink-discharge-port strings corresponding to ink materials having different color tones, a high-quality image having excellent gradation can be recorded, while reducing the cost of the apparatus and increasing the data processing speed by reducing the capacity of a memory for storing dot arrangement patterns. For that purpose, as a plurality of dot arrangement patterns for determining dot arrangement at output within a M×N-dot region for one input pixel, (1) patterns having a large number of gradation levels that can be represented (for example, nine gradation levels) and a high recording resolution (for example, 1,200 dpi (dots per inch)×2,400 dpi) are used for colors in which uneven stripes tend to be pronouncedly observed (for example, light cyan and light magenta), and (2) patterns having a small number of gradation levels that can be represented (for example, five gradation levels) and a low recording resolution (for example, 1,200 dpi×1,200 dpi) are used for colors in which uneven stripes tend to be less pronouncedly observed (for example, black, cyan, magenta and yellow).

摘要： An ink jet recording apparatus can reduce waste ink produced in marginless printing caused by overflow from an ink absorber. To realize this, each time the marginless printing is executed, the volume of waste ink produced by the marginless printing is cumulatively added up in order to control a total volume of the waste ink. The waste ink volume to be added up is determined by at least the kind of print medium or the print mode.

摘要： Printing on an area of a printing medium in which printing locations may be significantly deviated due to inaccurate feeding of the printing medium can be performed, without degrading image quality. Specifically, when lines in this area (second area) are printed using four scanning operations (passes) of a print head, a duty in masking process is set at zero for the scanning operation (pass A) after a change-line operation for feeding the printing medium with a possible large shift feeding error, and is distributed to other scanning operations. Thus, no dots are formed during this scanning operation (pass A), thereby preventing significantly deviated dots from being formed.

摘要： The present invention relates to an ink jet printing apparatus which sufficiently heats a head even in a low-temperature environment, which enables a proper image to be printed by stably ejecting ink, and which can be inexpensively and simply constructed. According to the present invention, if the detected temperature of a printhead is lower than a first heating threshold temperature, a heating mode in which the printhead can be heated is set before a printing operation. Further, when the heating mode is set and the detected temperature of the printhead is lower than a second heating threshold temperature, a heating unit heats the printhead. Consequently, even in a low-temperature environment, the heating operation keeps ink in a desired condition suitable for printing.

摘要： The present invention provides a method of printing a high quality color image with no color variations at high speed. For this purpose, this invention arranges in a main scan direction a plurality of print heads that eject different color inks, and reciprocally moves each of the print heads to perform a multipass printing in which a print operation is executed in both the forward and backward passes. During the multipass printing, the print duties of the print heads are set by mask patterns. Each of the mask patterns divides the print duty setting area for each nozzle group of each head into subdivided areas, sets the print duties of the subdivided areas to values different from each other and sets the print duties of the print heads to different values.
