摘要： The invention intends to maintain a constant ink discharge amount among the recording heads, even in case a total pulse width of pulse voltages applied to heat generating resistors. For this purpose, a rank table is prepared in such a manner, even in a situation where a total pulse width of the pulses applied to the heat generating resistor is 3 μs or less whereby the ink discharge amount decreases with a decrease in the total pulse width, that a maximum reached temperature on the surface of the heat generating resistors at the application of a preheat pulse becomes higher with a decrease in the resistance of a rank resistor, and a pulse width P1 on the rank table is made longer thereby compensating a decrease in the ink discharge amount with a decrease in the total pulse width and maintaining a constant ink discharge amount.

摘要： The object of this invention is to provide a printing apparatus and printhead temperature retaining control method capable of suppressing power consumption, and reducing degradation in image quality. To achieve the object, a printing apparatus for printing an image on a printing medium by discharging ink, executes the following processes. A first temperature adjustment process is executed to adjust the printhead temperature to a first adjustment temperature during the non-printing period in which preparation for printing the image is executed by discharging ink from the orifices. Additionally, a second temperature adjustment process is executed to adjust the printhead temperature to a second adjustment temperature during a printing period in which the image is printed on the printing medium by discharging ink from the orifices. The process is executed while providing a quiescent period without printhead temperature adjustment between the first and second temperature adjustment processes.

摘要： An ink-jet recording device is capable of correcting a recording position due to a leaning of a printing head and correcting of driving timing between multiple printing heads. Each nozzle row of a printing head is classified into multiple nozzle groups, and the driving timing of the nozzle groups other than the nozzle group serving as a reference of correction of the multiple nozzle groups is adjustable to correct for any leaning of the printing head. Moreover, in the event of performing the driving timing between printing heads, the driving timing of a non-reference printing head is adjustable relative to a reference printing head employed for leaning correction of multiple printing heads.

摘要： This invention has as its object to realize multi-pass print control which requires a short processing time by a simple arrangement. To this end, a printer according to this invention attains multi-grayscale print control by changing the number of dots to be printed on each pixel to overlap each other in multi-pass print control that prints the pixel in a plurality of scans. In this case, index patterns, each of which designates which of scans is to be used to print in accordance with the density level of a pixel, are prepared for respective pixel values. If a plurality of patterns are prepared for each pixel value, a pattern is randomly selected from them. An image is printed in accordance with a print pattern defined by the selected pattern.
