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 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 and an ink-jet printing method allow the printing of an image with high quality without causing a change in ink color formed on the printing medium while keeping the printing conditions constant regardless of changing of the number of nozzles to be printed and the amount of transferring of the printing medium. This printing is performed, for example, by restricting use of the number of nozzles, which belong to a nozzle row located on an upstream side in the sub-scan direction, before changing the amount of transferring of the printing medium; and restricting use of the number of nozzles, which belong to the nozzle rows located on a downstream side in the sub-scan direction, after changing the amount of transferring of the printing medium.

摘要： In a printer, when difference in ejection characteristic among nozzles appears as density non-uniformity and the way of letting the density non-uniformity appear is different depending upon kind of image, proper density correction is performed. Specifically, the kind of image to be printed is judged, and when the kind of image is a halftone image according to the judgment, a density correction table corresponding to the halftone image is selected and used to perform the density correction. Also when the kind of image is judged to be a solid image (without a portion of the halftone image), a proper table is selected similarly and used to perform the density correction.

摘要： A printing apparatus can reduce degradation in print quality of a printed image, notably in a highlight portion or an intermediate gradation portion, in the case where the image is printed by forming dots of a plurality of sizes. Specifically, data causing larger and smaller cyan ink droplets, respectively, to be ejected is independently subjected to a conversion to n-value process. Thus, the data for larger ink droplets is present in a portion of printing data which corresponds to the highlight portion or intermediate gradation portion of the image. During printing, larger dots are formed in this area, thereby making it difficult to perceive possible stripes caused by the offset of the positions at which smaller droplets impact a sheet.

摘要： An apparatus and method capable of obtaining an output characteristic of the print unit and determining a correction value for an output density, without using an expensive scanner. To realize this, a nozzle array consisting of a plurality of nozzles provided in the print head is divided into a plurality of nozzle blocks [a] to [d] and each of patches is formed by using the nozzles of the same nozzle block allocated to the patch. The patches are printed in a size and shape that allows the densities of the patches to be optically detected by the density sensor. A test pattern comprising these patches is measured by the density sensor to make a density correction for each nozzle of the print head.

摘要： In an image processing method, on the basis of input image data with respect to a target pixel, independent multi-level data (g0, g1) corresponding to respective plural species of dots which are different in at least one of a density and a diameter are generated, and then data (O0, O1) relating to an amount of generation of the dots with respect to the target pixel are generated on the basis of a relationship between the generated independent multi-level data (g0, g1) corresponding to the plural species of dots. The image processing method is effective in performing design having a high degree of flexibility in proper use of a relatively high power dot (high density dot or large dot) and a relatively low power dot (low density dot or small dot) and can realize obviation or alleviation of an occurrence of granulation or an apparent frame caused due to the relatively high power dot.
