Abstract: In an image-forming method, a device reads line data L for one line and determines whether the resolution of the line data L in the main scanning direction is greater than or equal to a threshold th. If the resolution is greater than or equal to the threshold th, then a multiple line process is performed on the line data L to divide this data into two sets of partial line data L1 and L2. The partial line data 'L1 and L2 are used to form two lines at locations shifted from each other in the sub-scanning direction. However, if the resolution of the line data L is smaller than the threshold th, then a single line process is performed to divide the line data L into two segments Q1 and Q2. The segments Q1 and Q2 of the line data L are used to form a single line at the same location in the sub-scanning direction by printing the segment Q1 in the first main scanning operation and by printing the segment Q2 in the second main scanning operation.

Abstract: An image-recording apparatus 1 comprises image recording assembly 60 and a control section 40 having image-processing section 44. The image-processing section divides the image data indicative of the complete image into a plurality of image data pieces indicative of divided images, detects two adjoining divided-images that individually have a joint portion and adjoin each other at the respective joint portions, in the divided images indicated by the divided image data pieces and rotates one of the adjoining divided-images so as to make a recording direction of one of the adjoining divided-images opposite to a recording direction of the other adjoining divided-image. The control section controls the image recording assembly so that a recording medium carries in one direction during recording all divided-images. The divided images are recorded on the respective recording-media one by one to form a plurality of output images. The plurality of output images configure one complete image.

Abstract: 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.times.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.

Abstract: 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.

Abstract: A process for recording information on a recording substrate, in which a print head with number (a) of printing elements moves back and forth over print positions, one print line at a time. Partial numbers of printing elements form subgroups in accordance with predetermined formations specific to the print lines. These subgroups are allocated to the print positions of a print line and are formed by at least partly differing printing elements. The individual printing elements of the respective subgroup are selectively controlled at the print positions in accordance with print data to produce a print pattern line. On completion of a subsequent print pattern line, the predetermined formation for a subsequent print line conforms, at least on the continuation side, to the predetermined formation of the preceding print line. Stripes caused by line continuation errors or ink ribbon structure errors are distributed throughout the printed image so as to be vertically offset. In contrast to uniform structures, structures which are distributed in this way can barely be discerned by the human eye.
