摘要： There is provided an inkjet printing apparatus which can restrict each of coloring of reflected light and image clarity within an allowable range required in each of a color mode and a monochromatic mode in any of the modes to output an image with a high grade. For this end, a print duty of each of the first image improving liquid and the second image improving liquid is set in such a manner that a ratio of the print duty of the first image improving liquid having low penetratability to the print duty of the second image improving liquid having high penetratability is higher in the monochromatic mode than that in the color mode. Thereby, an appropriate ratio and an appropriate amount of appropriate kinds of the image improving liquids are applied to each of the color mode and the monochromatic mode.

摘要： The use amount of clear ink is set to minimum the hue difference Δθs−d from each of the colors corresponding to input signal values. The use amount of the clear ink to provide the minimum hue difference Δθs−d is varied depending on the use amount of color ink used for the color corresponding to the input signal value. Then, a color conversion table having output values of the use amount and ink color data corresponding to the use amount is set. The color conversion in such a relationship is performed, whereby the bronzing color is recognized as a color close to the print color. As a result, undesired bronzing is lessened, so that degradation in image quality can be suppressed.

摘要： A printing apparatus and a printing method are provided by which, when an image is printed by a plurality of printing modes using different printing elements, a plurality of printing elements can have an equalized use frequency to thereby maintain the uniformity of quality of the printed image. In a first multipath printing control, a use rate of a nozzle group that is not used in the first multipath printing control and that is used in a second multipath printing control is higher than that of a nozzle group that is used in the first and second multipath printing controls.

摘要： The present invention suppresses a bronzing phenomenon that occurs easily in inkjet printing that uses pigment ink, and minimizes other effects on the image quality by particularly minimizing the change in gray balance. Of at least first and second achromatic inks having different densities of pigment coloring material, the amount of resin in the second achromatic ink (light gray ink) having the lowest density of coloring material is increased, and on the achromatic color axis, a specified amount of light gray ink is used up to gradations other than highlighted areas, and light gray ink is printed in scans after all the inks that include the second achromatic ink. As a result, it is possible to reduce the bronzing phenomenon.

摘要： An ink jet printing apparatus that can inhibit the possible degradation of image quality caused by variation in the conveyance amount of a print medium is provided. The ink jet printing apparatus includes a detection section detecting the conveyance amount of the print medium, and a print head position adjusting section slightly moving a print head in a conveyance direction of the print medium. The print head position adjusting section adjusts the position of the print head in the conveyance direction according to an error in the conveyance amount of the print medium detected by the detection section. Thus, printing can be performed at the head position adjusted with the error in conveyance amount taken into account. Therefore, the possible degradation of the image quality caused by a conveyance variation can be inhibited.

摘要： A method (300) is described of determining characteristic of an ink jet printer (15). A chart containing multiple regions or patches is printed (320) on a print medium (115) using the ink jet print (15). The chart includes at least a first region printed using a first set of nozzles, and at least a second region printed using a second set of nozzles. The first and second sets of nozzles are a predetermined distance apart in the printer head of the printer (15). The printing of the first and second regions is also separated by a print medium advance operation equal to the predetermined distance. This causes the first and second regions to be aligned in the direction of the print medium advance operation. The chart is then imaged using scanner (16) chart to form a chart image. The positions of the regions appearing in the chart image are next determined (340). The spatial alignment characteristic of the printer is calculated from the distance, in the medium advance direction, between said first and second regions.

摘要： In a supply system which includes an ink container for reserving a predetermined amount of ink to be supplied to a printing head and which is configured such that ink is intermittently supplied to the container from an ink tank, there is provided a structure that fundamentally eliminates waste of ink associated with an operation of charging the container to apply a required negative pressure to the head. An ink containing body in which a negative pressure can be generated because of its elasticity is provided in the container. After the ink containing body is expanded to introduce ink into the same by depressurizing the interior of the container, the interior of the container is pressurized to contract the ink containing body, thereby returning a predetermined amount of ink to the tank. A negative pressure is thus generated in equilibrium with an ink meniscus holding ability of the head.
