摘要： An ink jet recording apparatus adjusts at least one of a preliminary discharge time representing a time until the subsequent preliminary discharge is performed and a compensated time determined on the basis of the time elapsed since the previous preliminary discharge, so that the preliminary discharge is performed at a predetermined preliminary discharge hole. Accordingly, the ink jet recording apparatus is capable of recording on different kinds of recording media in a manner suitable for each of them without using a complex control process, and of performing the preliminary discharge according to the size of the recording media. In addition, a reduction in the throughput is prevented by using the ink jet recording apparatus.

摘要： The present invention provides a printing apparatus and method that can prevent the image grade from lowering. A print head is provided with a plurality of printing elements to print dots on N adjacent rasters and dots on M adjacent columns under different conditions by causing the print heads perform a plurality of (P) main-scanning operations in a main-scanning direction and transporting a printing medium at least once in a sub-scanning direction. A plurality of dot arrangement patterns used for the same level of image data are periodically changed. The plurality of dot arrangement patterns are such that within each period when the patterns are repeatedly used, the number of dots formed in each of said N rasters are equalized, whereas the number of dots formed in each of said M columns are equalized.

摘要： A printing method capable of printing a high-quality image at a high speed and low cost and a corresponding printing apparatus are disclosed. In this printing apparatus, a shading-corrected mask pattern for multipass printing control in consideration of the characteristics of each printing element of a printhead is generated. The size of the mask pattern in the conveyance direction of the printing medium is set to be an integer multiple of the conveyance amount of the printing medium per scanning of the printhead. Image data masked using the mask pattern is transferred to the printhead and printed. Alternatively, the conveyance-direction size of the mask pattern for masking print data in accordance with each pass printing of multipass printing is set to be equivalent to the number of nozzles of an ink-jet printhead having a plurality of nozzles arrayed in the conveyance direction of the printing medium, and the mask pattern is dividedly used for each pass printing. Any error of the position of a dot printed on the printing medium by an ink droplet discharged from each nozzle is detected in units of nozzles. Printing may be performed using a mask pattern generated such that a printing element with a small error is frequently used in accordance with the detection result, or performed such that the positions of print data are exchanged.

摘要： In an ink-jet printing apparatus which includes a plurality of printing heads, each having an array of ink discharging elements, preliminary discharge of driving the elements of at least one printing head is performed a predetermined number of times. The printing head for which the preliminary discharge is to be performed is switched in a predetermined cycle. In performing the preliminary discharge, switching of the printing head is so controlled as to perform preliminary discharge a desired number of times for all the elements of the printing heads by repeating the cycle.

摘要： Even if a recording medium is interfered with an opposed surface of a carriage and/or a recording head due to the curl of the recording medium, damage of the recording medium and the recording head is prevented by avoiding collision between an edge of the recording medium and the carriage and/or the recording head. The opposed surface (opposed to the recording medium) of the recording head 1 or the carriage is made smooth to form a smooth portion, and a moving range of the carriage is limited so that the smooth portion is not moved out of the recording medium, and a preliminary discharge receiving portion for receiving ink discharged to recover the recording head is disposed within the moving range of the carriage, and the moving range of the carriage is controlled to be limited when it is judged that curl will occur in the recording medium.

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： 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： A contamination of a printing medium caused by ink mist or the like is suppressed, which may scatter or float in an apparatus when margin-less printing is carried out in an ink jet printer. When margin-less printing for an edge of a printing medium P is performed, a predetermined edge area {circle over (1)} is printed using a smaller number of ejection openings during one scanning operation than that used for other areas {circle over (2)} and {circle over (3)}, while taking transportation errors relating to this end into consideration. This reduces the amount of ink mist resulting from ink ejected out of the edge of the printing medium during one scanning operation.
