摘要： Graininess is suppressed while at the same time minimizing grayscale variations caused by inter-plane deviations. For this purpose, when a pixel is printed by M relative scans of a print head over a print medium or by a relative scans of M print heads over the print medium, M pieces of multivalued image data is created according to a division number or distribution ratio determined by a grayscale value of that pixel. The M pieces of multivalued image data are individually quantized and then the printing is performed according to the quantized pixel data. This process prevents dot generation delays and graininess from deteriorating in highlighted areas, thus realizing printed images highly robust against density variations.

摘要： When executing the gradation lowering processing to a data area in the lower side in multi-valued print data 403, an error generated by executing the gradation lowering processing to the data area in the lower side is stored in an information storage area 901B. On the other hand, the error thus distributed and stored is used for executing the gradation lowering processing to the data area “J” (Jth line) in multi-valued print data 404 relating to the next scan. In this way the error generated when executing the gradation lowering processing to the multi-valued print data is stored, which is used at the time of executing the gradation lowering processing to the multi-valued print data relating to the next scan. Therefore, the density is stored by receiving and delivering the error between the multi-valued print data in a scan unit.

摘要： A spliced ink-jet head including head chips, each of which is capable of discharging inks of two or more colors, and which are spliced in a staggered manner which restrains the occurrence of splice streaks, white streaks caused by deflection at ends or uneven colors attributable to different landing orders of ink droplets in spliced portions of different colors when one-pass recording is carried out. The head chips is arranged such that, in a relationship between two adjoining head chips, at least one discharge port of one head chip and one discharge port of the other head chip for the same color tone ink in end portions overlap on a line in a recording material feeding direction, while discharge ports for different color tone inks do not overlap.

摘要： A printing apparatus executes printing by arranging plural printheads, each including a plurality of print elements in a direction of a print width so as to obtain the print width corresponding to a width of a printing medium and conveying the printing medium in a direction perpendicular to the direction of the print width. The printing positions of part of the print elements of a first printhead in the direction of the print width overlap with part of the print elements of a second printhead in the direction of the print width. The apparatus includes a conveyor for conveying the printing medium, a mutual complementary printer performing mutual complementary printing in the overlap portion by the overlapped print elements, and a time divisional driving controller for dividing the plurality of print elements of each of the plural printheads into a plurality of blocks, with each block composed of a predetermined number of print elements, and for time-divisionally driving the predetermined number of print elements included in each block. The predetermined number differs from a number of print elements included in the overlap portion, and the time divisional driving controller controls the driving sequences of the overlapped print elements of the plural printheads to coincide with each other.

摘要： In an ink jet printing apparatus that adopts an area grayscale system using halftone elements, this invention prevents degradations of grayscale reproducibility caused by a plurality of dots pulling each other on a print medium, and thereby realize a stable grayscale and color reproducibility. To this end dots to be applied to halftone elements, whose arrangement is determined by the halftone element-based area grayscale system, are divided into a dot group for interior halftone elements and a dot group for outline halftone elements. These two dot groups are printed with a predetermined time difference between them. The subsequent dots are then drawn to the preceding dots that are not yet absorbed in the print medium. Therefore, the overall shape and grayscale level of the merged dot in each pixel become stable, allowing for reliable image processing which in turn realizes excellent grayscale and color reproducibility.

摘要： High quality images showing an excellent fixation are formed by an ink-jet recording method using pigment inks. An ink set for the ink jet-recording method comprises a first ink containing an anionic dye in an aqueous medium, a second ink containing an anionic dye and having a lower coloring material content than the first ink and a dispersion destabilizing substance, and a third ink containing a self-dispersible first pigment, a second pigment and a polymeric dispersant for dispersing the second pigment in an aqueous medium. The dispersion destabilizing substance destabilizes the dispersion stability of at least either the first pigment or the second pigment in the third ink when the second ink and the third ink are brought into contact with each other. The second ink and the third ink are applied onto a printing medium one after another or substantially simultaneously so that they are brought into contact with each other in a liquid state on the printing medium.
