摘要： Disclosed is an inkjet printing apparatus for forming an image by repeatedly causing the scanning of a printhead that prints an image in a scan area using inks of a plurality of types. Residual duty, which is obtained by quantifying the mixed state of the inks used in printing the image in the scan area, is defined. The residual duty with regard to the next scan area is found from image data, the scanning direction for printing in the next scan area is decided based upon the residual duty, and the area is printed in the scanning direction that has been decided. Thus, back-and-forth scanning and unidirectional scanning are used jointly in appropriate fashion in accordance with the printed image. As a result, high-quality printing of an image becomes possible and a higher printing speed is achieved.

摘要： An ink jet printing apparatus and an ink jet printing method according to the present invention suppress a variation in the density of ink in a supply channel and a print head without the need for useless recovery operations, thus always providing very reliable high-grade images. The ink jet printing apparatus carries out printing using a print head for ejecting ink. The apparatus includes a scanning unit for causing the print head to scan across a printing medium, a measuring unit for measuring a time from an end of a preceding printing operation until a start of a current printing operation, and a determining unit for determining whether or not a result of measurement executed by the measuring unit exceeds a predetermined value. The scanning unit causes the print head to carry out at least one idle scan before the start of a printing operation depending on a result of determination made by the determining unit.

摘要： Gradation data for each color to be input to a recording apparatus includes dot-recording-position information for every unit pixel and information for determining a nozzle position in a recording head for recording a dot. The information for determining the nozzle position makes determination in accordance with image data of an ink with resin and image data of an ink without resin. In a region where the ink with resin and the ink without resin overlap with each other, the ink without resin can land first.

摘要： One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio.

摘要： The present invention provides an ink jet printing apparatus, an ink jet printing method, a data generation apparatus, a computer program, and an ink jet printing system by which a timing for ejecting a processing liquid can be changed to improve image performance of a printed image such as abrasion resistance, to provide the printing head with a longer life, and to improve a throughput. The processing liquid is ejected to a predetermined area on a printing medium, for which a formation of an image by ink is completed, in two or more scannings among five scannings of the printing head. When an amount of ejection data for ejecting the processing liquid in the fifth scanning for ejecting only the processing liquid is equal to or lower than a predetermined amount, the fifth scanning is not carried out.
