摘要： By ejection from each ejection opening of a liquid ejecting head, predetermined lengths of ruled line patterns are formed in order, and by ejection of an ink from an ink ejecting head, a solid pattern is printed overlaying the ruled line patterns of the liquid. In this case, the portion corresponding to the ejection opening through which the liquid cannot be ejected may be a different printing density in comparison with another portion where the liquid and the ink are overlaid. By this, non-ejection failure at the ejection opening can be detected. Therefore, in an ink-jet printing apparatus employing a head for ejecting the liquid for making a coloring agent in the ink insoluable for enhancing water resistance, the ejection condition of the head can be successfully detected.

摘要： In an apparatus for recording color images making use of a plurality of inks of different colors (Y, M, C, K), the penetrability of at least one ink is caused to differ from that of the other inks. In particular, the penetrability of an ink higher in lightness is made higher than that of another ink lower in lightness. For example, inks are prepared in such a manner that their penetrability becomes higher in the order of K

摘要： An ink jet recording apparatus and ink jet recording method record using different kinds of ink each having the same series color and a different density. The jet recording apparatus includes a converting unit for converting an input image density signal into an output image density signal, a binary unit for converting the output image density signal into binary data, an inverting unit for inverting the binary data, and a distributing unit for the binary data inverted and binary data to be inverted to drive data for an ink discharge unit and drive data for another ink discharge unit. Density unevenness and texture which arise from an image process, particularly a binary process, can be prevented. Different kinds of ink, each of which has the same series color and a different density, are respectively scanned so as not to overlap on the same pixel. Density unevenness due to ink soaking can be suppressed because different kinds of ink each having the same series color and a different density are not shot at the same position.

摘要： The present invention is designed to make uniform frequencies with which individual recording elements of a multihead are used in a recording apparatus for performing gray scale recording by controlling a number of dots recorded in a unit area. A gray scale pattern used to display gray scale is a pattern in which a plurality of blocks each comprising a dot concentration type gray scale pattern having a size smaller than that of the gray scale pattern is dispersed. The maximum difference between numbers of times the recording elements in the range of the gray scale pattern are used can be restricted within twice, and individual nozzles can be used uniformly. Consequently, imbalance of changes in the recording elements with time, caused by the differences between the frequencies with which the recording elements are used, can be restricted, thus restricting irregularities on an image.

摘要： A recording head having an ejection portion group for ejecting a black ink, and ejection portion groups for ejecting color inks is used. When a black image to be printed by the black ink is present adjacent to a color image to be printed by the color ink, a black image portion adjacent to the color image and a black image portion which is not adjacent to the color image are formed in different scans, thereby obtaining a high-quality image from which ink blurring at a boundary portion between the black and color images is eliminated.

摘要： A liquid ejection method involves supplying liquid along a heat generating element disposed along a flow path from upstream of the heat generating element, applying heat generated by the heat generating element to the thus supplied liquid to generate a bubble, thus moving a free end of a movable member having the free end adjacent the ejection outlet side by pressure produced by the bubble, the movable member facing the heat generating element, supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween, pre-heating the liquid by the first pulse to an extent insufficient to eject liquid through the ejection outlet, and generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet. The method also includes ejecting liquid in an amount determined by controlling a degree of pre-heating of the liquid by changing at least one of a width of the first pulse or the interval time. The change rate of the ejection amount of the liquid increases non-linearly with an increase of the width of the first pulse or an increase of the interval time period. Recording heads and apparatuses control the ejection amount of liquid in like manner.

摘要： The first print data indicating the discharging amounts of color and clear inks is generated in correspondence with an image to be printed with the color and clear inks. The second print data for designating a region for expressing decoration is generated. The discharging amount of the clear ink in the region for expressing decoration in the first print data is changed based on the second print data. Printing is done by scanning a printhead a plurality of number of times based on the changed first print data to execute the print scan of the clear ink after that of the color ink.
