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： The present invention provides a liquid application device and an inkjet recording apparatus, which are capable of supplying liquid to a liquid room with the power consumption and/or the noise which are reduced. A pump is driven to fill a liquid retention space S with an application liquid. When the filling has been completed, the pump is stopped. Subsequently, the application liquid is applied to an application medium which has been transferred. At this time, a count in a RAM is increased. Thereafter, the determination as to whether or not the application can be carried out is made on the basis of the count and the prescribed application-performable number of sheets stored in a ROM. If it is determined that the application cannot be carried out, the filling of the application liquid is performed. If it is determined that the application can be carried out, next application is performed.

摘要： An adjustment value applicable to the adjustment of a printing position is obtainable by reading a printing position adjustment pattern printed on a printing medium without requiring the manual operation by the operator. Furthermore, the printing position can be optimally adjusted by accurately scanning the printing position adjustment pattern. For this purpose, an optical sensor is located in the vicinity of the printing head, and the optical sensor is situated near a predetermined position side. The predetermined position side is a pinch roller side where a large restrictive force acts to the printing medium with the printing position adjustment pattern printed thereon.

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： A controller generates printing data to be printed by the printing nozzles of at least first and second adjacent printing nozzle arrays out of a plurality of printing nozzle arrays on the basis of tone information of image data to be printed. In particular, the controller generates printing data to be printed by each of the first and second printing nozzle arrays in the range in which the influence of an air flow generated along with ink discharge from the first and second printing nozzle arrays is admissible. Printing by the first and second printing nozzle arrays of the printhead is controlled on the basis of the generated printing data.

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： By making judgment whether number of dots to be printed in one printing scan exceeds a predetermined criterion or not, printing elements associated with summing of number of dots are selected if the number of dots exceeds the predetermined criterion, printing scan for the scanning lines corresponding to the selected printing elements is performed, and paper feeding for the printed scanning line is performed. By this, possible largest number of scanning lines can be printed within an allowable electric energy consumption for one scan. Thus, efficient printing operation can be performed.
