摘要： An ink jet printer includes a distance adjust mechanism for adjusting in two steps a distance between a liquid nozzle-formed face of a print unit and the recording surface, and a unit having first and second cleaning members with different free end positions, lengths and/or thicknesses are arranged movable relative to the face and adapted to wipe a substance adhering to the face off of the face with a predetermined engagement condition. The substance is wiped off of the face by the first and second cleaning members having different engagement conditions when the face is a first distance from a recording surface, and is wiped off with the engagement condition of a wipe portion of the first cleaning member virtually equal to the engagement condition of a wipe portion of the second cleaning member associated with the first distance when the face is a second distance from the medium. Further, a height difference between the cleaning members is set almost equal to the distance the face is moved by the distance adjust mechanism.

摘要： When recording a gradation pixel by performing pseudo-halftone processing, the occurrence of unevenness in the density in the recorded image is suppressed. For that purpose, when recording a pseudo-halftone image using dot patterns, a dot-pattern table storing a plurality of different dot patterns is provided for each gradation value. One dot-pattern table is selected from N dot-pattern tables based on gradation-value information for each pixel. One dot pattern is selected from the selected dot-pattern table, based on position information indicated by the pixel, and recording is performed using the selected dot pattern. It is thereby possible to prevent the concentrated use of a particular nozzle of a recording head, and suppress the occurrence of unevenness in the density due to characteristics of the specific nozzle.

摘要： When highly redundant information that expresses five tones using 4 bits is transferred to a printer in terms of a unit data length in data transfer, efficiency is very poor. Hence, multi-valued data is quantized to 5-valued data, which is output as a 4-bit code that can express five values. 4-bit codes for three bits are combined to be converted into an 8-bit code. The 8-bit codes are packed into data of a 16-bit unit, and the packed data is transferred to the printer.

摘要： An ink-jet printing apparatus, for printing an image based on image information on a printing medium by relatively moving an ink-jet printhead, detects the temperature of the ink-jet printhead by using a head temperature detection unit and outputs it to a driving frequency determination unit. The driving frequency determination unit acquires temperature information in units of pages of image information or predetermined image areas. If the acquired temperature is equal to or higher than a predetermined temperature, the driving frequency of the ink-jet printhead is decreased when a predetermined unit of the image information is printed.

摘要： By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered; and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the plurality of adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

摘要： An apparatus and method are provided to enable high speed printing of an image with high resolution while suppressing degradation of image quality due to white stripes and density variations. In an ink jet printing apparatus using a multi-pass printing system, the same scan print area is divided at a predetermined pitch and the printing duties of the divided areas determined by the thinning out mask pattern are set to different values. In regard to the same scan print area formed by a plurality of the main scans, the divided areas corresponding to the ends of the print head have their printing duties set smaller than those of the divided areas on the inner side of the ends of the print head.
