摘要： If print agents used are detected by an optical sensor at different sensitivities, the present invention enables the easy setting of adjustment values for print positions resulting from these print agents. To accomplish this object, for example, the present invention substitutes and sets adjustment values for print positions resulting from cyan, light cyan, or black ink, corresponding to a high detection sensitivity, for adjustment values for print positions resulting from a light magenta, yellow, or magenta ink, corresponding to a low detection sensitivity.

摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： A printing apparatus and a preliminary discharge control method are capable of efficient preliminary discharge control even in a case where a time interval to assure normal printing is equal or nearly equal to the period of one print scanning of an inkjet printhead. In the method, in an inkjet printhead which performs printing by discharging ink from plural print elements while being reciprocate-scanned by a carriage, the number of ink dischargings from each of the plural print elements is counted during print scanning by reciprocate scanning. It is determined whether or not the counted number of ink dischargings from each of the plural print elements is equal to or greater than a predetermined number at predetermined intervals. In accordance with the result of determination, a printable period is updated, and the updated printable period is compared with time necessary for the next print scanning upon completion of one print scanning by reciprocate scanning. Then, in accordance with the result of comparison, preliminary discharge is performed from the inkjet printhead.

摘要： An ink-jet recording apparatus ejects ink droplets having two sizes, a large size and a small size. The ink-jet recording apparatus records data with a pattern assigned to quantized data. This arrangement reduces density non-uniformity and streaks related to the landing accuracy of ink droplets, the accuracy of sheet conveyance in the recording apparatus, and the accuracy of carriage scanning. Recording is performed with large and small dot-matrix patterns assigned to quantized data on independent planes. When the large dot and the small dot in a pattern are provided to one pixel at the same time, the large dot and the small dot are placed in positions not overlapping in the one pixel.

摘要： A print apparatus that, without significantly reducing an overall printing speed, allows a reduction in uneven densities due to the discharge time difference between black ink and color inks, which occur particularly at both ends in a scanning range and which are caused by the printing by bidirectional scanning of print heads, and enables high image-quality printing to be realized. In this print apparatus, one band is divided into plural areas in a main scanning direction, the dot numbers of black ink and color ink imparted to respective areas are counted. If there are any areas where the dot numbers of both black and color exceed respective threshold values, the area number is counted, and if the number exceeds a predetermined number, the print mode is switched from bidirectional printing to a unidirectional one, upon determining that there is a high probability of occurrence of the above-described uneven densities.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, when symmetrically arranged ejection opening rows for a cyan, magenta, and yellow inks are used in the print head, one-pass bidirectional printing is executed. On the other hand, if ejection opening rows for a black ink are used in addition to the above ejection opening rows, multi-pass printing is executed so that there are a number of dots formed with one application order for the black and other color inks and the same number of dots formed with another application order for the black and other color inks. This reduces the non-uniformity of the colors attributed to the difference in application order.
