摘要： A printing apparatus and a print position aligning method are provided which can execute a dot position adjust value calculation mode normally and smoothly without requiring the user to make decisions or adjustments. A test pattern to check the width of a print medium is printed and is detected by an optical sensor to decide whether or not a dot position adjustment pattern can be printed. Before the dot position adjustment pattern is printed, a decision is made as to whether the print medium supplied is appropriate or not. If the print medium supplied is smaller than a size specified for the dot position adjust value calculation processing, the print medium is discharged without being printed with the dot position adjustment pattern. This eliminates a possibility of a wasteful consumption of print mediums and of contaminating the interior of the printing apparatus.

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： 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.

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： According to the present invention, 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： A print method that uses a printer apparatus based on a multi-pass printing method to reduce the unevenness of colors associated with a scanning direction, even during bidirectional color printing. For this purpose, sets of two print heads that apply cyan (C), magenta (M), and yellow (Y) inks are arranged to be symmetrical in the scanning direction so that a plurality of secondary color pixels arranged in a raster direction can be formed by changing an ink application order (C→M and M→C). Consequently, the pluralities of secondary color pixels arranged in the raster direction undergo the different ink application orders, so that the application order remains the same whether the pixels are formed during forward or backward scanning. Therefore, the unevenness of colors associated with the ink application order can be reduced.

摘要： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.
