    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： 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. Codes of the respective color data of print data are determined in accordance with the types of inks used for a print operation, and an image is printed by printing a plurality of dots or dots in an overlapping state by the multi-pass method.

    摘要： An ink jet recording apparatus records by supplying heat energy according to a drive pulse to an ink to form a bubble based on film boiling and ejecting the ink from a recording head onto a recording medium based on formation of the bubble. The ink jet recording apparatus includes a driver for supplying a pre-driving pulse that does not cause ink ejection and a main driving pulse that causes the ink ejection with a rest period between the two pulses for ejection of one ink droplet, and a rest period controller for controlling the rest period within a range where an amount of the ink ejection increases in accordance with an increase of the rest period. Controlling the rest period controls an amount of the ink ejection, with the rest period based on a temperature of the recording head. Also, a temperature of the recording head is obtained by calculating the energy input to the recording head by the supplied driving pulses.
