摘要： The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.
摘要翻译：在使用多种类型的墨水进行双向打印的喷墨打印装置中，如果用于黄色，品红色和青色墨水的排出开口行对称地布置，则用于黑色墨水的排出开口排布置成与最内侧的排出开口行相邻，黄色的墨水。因此，通过黑色墨水和黄色墨水之间的着色差异来确定正向扫描和反向扫描之间的颜色差异。在这种情况下，通过选择墨水可以抑制归因于双向印刷的可能的颜色漂移，使得黑色墨水和黄色墨水之间的着色差异小于黑色墨水和其它颜色墨水之间的着色差异。

摘要： There are provided an image processing method and an image processor which realize the processing of restricting image degradations such as “dot delay”, “banding” and “wind ripple” with a simpler circuit construction. Therefore, after the regular quantization processing is performed, in a pixel in a prohibition position the processing of limiting a predetermined quantized value to change into another quantized value is performed corresponding to the obtained quantized value and the position information of the pixel of interest. By doing this, even in the low level of the density value, it is possible to realize at a low cost the construction in which dots having different sizes are mixed for printing.

摘要： A voltage pulse that keeps the ejection volume within a specified range is selected for a plurality of print element columns, based on the heater rank and ink temperature information that influences the ejection volume during ink ejection. At this time, the voltage pulse is controlled so that the voltage value of the pulse is equal for a plurality of print element columns at any ink temperature and varies according to the ink temperature. This control process enables pulses of the same voltage value to be applied at all times to a plurality of nozzle columns even if these nozzle columns in the print head have different heater ranks. As a result, the ejection volumes of all nozzle columns can be kept within a specified range with high precision over a wide range of base temperature, without requiring complicated circuit configurations.

摘要： The sequence of the acquisition of a correction value of a conveying error depending on the eccentricity of the conveying roller (correction value for eccentricity) and the acquisition of a correction value of a conveying error depending on the outer diameter of the roller (correction value for outer diameter) is considered to acquire a precise correction value for outer diameter. A test pattern to acquire the correction values for eccentricity and for outer diameter is formed with an area exceeds the area corresponding to an integer multiple of the circumferential length of the roller. The correction value for eccentricity and that for outer diameter are acquired in this sequence. The fluctuation in the conveying error is reduced by the application of the correction value for eccentricity, and the influence of the excess area is made smaller before the correction value for outer diameter is acquired by averaging the conveying errors.
