摘要： A recording scan is performed through a relative reciprocation of color recording heads on a recording material. The recording heads can record with higher recording density than that of input image date. A plurality of pixels (2.times.2)are formed for each pixel of input image data. A mixed color image is recorded by multiple scans of the recording heads, in such a manner that pixels thereof (2.times.2) are not subjected to superposition of ink of two colors or more during a scan of the recording heads. Thus, it is possible to prevent an occurrence of variations in mixed color, and to record a high quality color image without increasing a recording time. Further, an amount of ink of one color may be reduced when recording a second one of the scans.

摘要： A plurality of recording heads for ejecting inks of different colors are reciprocally moved relative to a recording medium, and printing operations are performed by executing main scans in forward and backward scans of the recording heads. In this case, an area printable in a single main scan is recorded by performing a plurality of main scans using a plurality of thinning patterns in which an m×n pixel group is defined as a unit pixel group, and the pixel groups are arranged at non-neighboring positions, and which have a complementary arrangement relationship therebetween. A high-quality color image free from time difference nonuniformity, and density nonuniformity caused by, e.g., variations of recording elements is obtained at high speed.

摘要： A recording head having a plurality of ink discharge element lines arranged thereon is moved in a direction different from the direction of arrangement of the ink discharge elements to conduct a main scan, and at the end of the main scan, a recording medium is moved by a predetermined width in a direction different from the main scan direction to record an image. A record area of the recording head is divided into a plurality (n) of areas and each unit image area on the recording medium is main scanned n times by using the n divided areas of the recording head and thinned images with a print factor of 1/n are sequentially recorded to complete the record of the unit image area. The print factor for the pixels in the boundary area of adjacent unit image areas is lower than the print factor to the entire unit image area in at least one of the n main scans. Thus, the number of pixels recorded by the same main scan in the boundary area is increased. A high quality image without a joint stripe is attained even for a recording medium having a relatively high ink absorption speed.

摘要： A plurality of recording heads for ejecting inks in different colors are aligned, and are reciprocally moved in the alignment direction, and an image is recorded by performing main scans in both the forward and backward paths of the reciprocal movement, and performing a sub-scan after each main scan. An area recordable in a single main scan is thinned out according to thinning arrangements having a complementary relationship therebetween, and thinned-out images are recorded in a plurality of main scans. During this interval, the sub-scan is performed in a direction opposite to the normal sub-scan direction at a predetermined period.

摘要： An ink jet head supplies an ejection heater arranged in a liquid path with a driving signal to impart heat energy to ink to thereby generate a bubble therein. The bubble is caused to communicated with the atmospheric air, and ink is ejected through an ejection outlet. A heat keeping circuit supplies the ejection heater with a driving pulse having a time width insufficient for causing ink to be ejected during non-printing period in an appropriate duty corresponding to the head temperature condition, thereby causing the ejection heater to generate heat to effect heat keeping on the head, whereby a low-cost thermal ink jet printing system is provided which does not entail a variation in ejection amount during printing.
