摘要： A printing apparatus and print control method, capable of using plural types of printheads, can achieve high throughput by performing optimized print control in accordance with the type of printhead and the number of printheads used. In a case where the printing apparatus adopting such print control method includes, e.g., four printheads, and performs printing on a print medium by reciprocally scanning the printheads, detection is first performed as to whether only one printhead which discharges black ink is mounted or four printheads which respectively discharge black, yellow, cyan and magenta ink are mounted; decision is made on a printing period of the printhead based on the detected result; then decision is made on a scanning speed of the printhead based on the decided printing period; and the printhead is driven based on the decided printing period and scanning speed to perform printing.
摘要翻译：能够使用多种类型的打印头的打印设备和打印控制方法可以通过根据打印头的类型和使用的打印头的数量执行优化的打印控制来实现高产量。在采用这种打印控制方法的打印设备包括例如四个打印头的情况下，并且通过往复扫描打印头在打印介质上进行打印时，首先执行检测是否仅安装一个排出黑色墨水的打印头或四个安装分别排出黑色，黄色，青色和品红色墨水的打印头; 基于检测结果在打印头的打印周期进行判定; 然后基于所决定的打印周期对打印头的扫描速度进行判定; 并且基于所决定的打印周期和扫描速度来驱动打印头以执行打印。

摘要： Each nozzle of an ink-jet head has heaters having different heating capacities, and in accordance with the heater driven, a diameter of an ink dot formed by ink which is discharged from the nozzle is changed, thereby printing a large dot or a small dot. When multi-value image data is inputted, the multi-value image data is modulated such that a pixel having high density is printed with both the large dot and small dot. On the basis of the modulated print data, any of the heaters included in each nozzle of the ink-jet head is driven, whereby printing an image having tones based on the multi-value image data.

摘要： Multi-valued image data is separated into data in units of nozzle groups of the individual colors of a printhead, and each divided multi-valued image data is converted into n-valued image data consisting of a plurality of bits. Based on the n-valued image data of the corresponding colors, print codes are generated and are transmitted to a printer apparatus. The printer apparatus receives the print codes, stores them in print buffers of the corresponding colors, and generates print data based on the print codes using mask patterns set in correspondence with image data of the individual colors. The print timing in each scan of the printhead is determined in accordance with the significant bit position in the print data, and an image is printed on the basis of the print data by multi-pass printing.

摘要： Disclosed are an inkjet printing method and an inkjet printer capable of printing high-quality images by the inkjet printing method even when ink is exchanged for ink having a different density, particularly ink having a lower density. A printer using this method identifies the type of an ink tank attached to a printhead. When the printer detects in accordance with the type of an ink tank that an ink tank is changed to another ink tank containing ink with a different density, recovery conditions for the printhead are changed in accordance with the type of the ink. Especially when an ink tank is exchanged for another ink tank containing ink with a lower density, the printer increases the number of times of suction for the printhead after the ink tank exchange and the number of times of preliminary discharge after wiping. The printer also shortens preliminary discharge intervals and increases the number of preliminary discharge times at the time of printing.

摘要： It is checked whether an ink used in a printhead has a high density. The type of a printing medium used for a print operation is also identified. An image is printed by scanning the printhead once or a plurality of times. When a print operation is to be performed by using a thick ink, an image is printed by using mask data and the driving frequency of the head which are set for the thick ink. When a print operation is to be performed by using a thin ink, an image is printed by using mask data and the driving frequency of the head which are set for the thin ink and the type of printing medium used for the print operation.

摘要： A printing apparatus and a printing registration method permits printing registration between a forward and a reverse scan of a head cartridge between a plurality of head cartridges without troubling a user and simply. By forward and reverse scan of the head cartridge, a plurality of patterns, in which a print start timing of the reverse scan is shifted per a predetermined amount relative to that of the forward scan, are printed. These patterns may vary an area factor by the dots formed by printing depending upon offset amount. On the other hand, the plurality of patterns are optically read an average density. By this, the timing, at which the read average density is maximum is set as the printing registration condition.
