Abstract: A printing apparatus has: ink-ejecting section units, each ink-ejecting section unit having ink-ejecting sections each being provided for ejecting an ink of a different color based on a gradation value that has been converted; a memory for storing darkness-correspondence information that correlates, for each ink color, darkness of images each printed using a different one of predetermined ink-ejecting sections each having an ink-ejection amount different from one another, and a darkness of an image printed using a reference ink amount; and a converting section for converting, for every pixel, a gradation value of image data to be printed, based on a correlation in the darkness-correspondence information between a darkness of an image printed using the predetermined ink-ejecting section that ejects an amount of ink that corresponds to an average value of the ink-ejection amounts respectively ejected from the ink-ejecting sections, and the darkness of the image printed using the reference ink amount.

Abstract: A printing method includes: preparing a printing apparatus provided with a carry unit that carries a medium in a carrying direction, and a plurality of nozzle groups that have respectively a plurality of nozzles lined up in the carrying direction; and printing an image to be printed on the medium by alternately repeating a dot forming process for forming dots on the medium by ejecting ink from each nozzle of a plurality of the nozzle groups that move in a moving direction, and a carrying process for carrying the medium in the carrying direction, and forming a plurality of rows of dots, lined up in the carrying direction, that are configured by a plurality of dots lined up in the moving direction, wherein in a case a certain row of dots is formed by a plurality of the nozzles, if, of a plurality of the nozzles that form the certain row of dots, the number of nozzles of a certain nozzle group is smaller than, of a plurality of the nozzles that form the certain row of dots, the number of nozzles of another nozzl

Abstract: An inkjet printer performs printing by scanning a printing head having a plurality of ink nozzles, and has a monotone printing mode and a color printing mode. Under the condition of using the same print medium and the same printing resolution, the average pass count for the monotone printing mode is set to a larger value than the average pass count for the color printing mode.

Abstract: There is provided a plurality of dot printing modes each defining printing operations during main- and sub-scanning. A preferable dot printing mode is selected according to mode selection information that is predetermined to specify the preferable printing mode, and printing is executed according to the preferable dot printing mode specified by the mode selection information. The plurality of dot printing modes are divided into a plurality of printing mode groups according to combination of print resolution and printing speed. The mode selection information specifies the preferable dot printing mode for each printing mode group. One of the plurality of printing mode groups is selected in initial settings of the printing apparatus.

Abstract: In the bi-directional printing, a reference correction value is set for correcting printing positional deviation arising between forward and reverse main scanning passes with respect to specific reference dots. An adjustment value is determined, using at least the reference correction value, to reduce printing positional deviation arising between forward and reverse main scanning passes. The printing positional deviation between forward and reverse main scanning passes is adjusted using the adjustment value. In a first adjustment mode, the adjustment value is determined by correcting the reference correction value with a relative correction value prepared beforehand for correcting the reference correction value.

Abstract: An ink jet recording head is provided with a nozzle formation face on which nozzles for ejecting ink drops in accordance with print data are formed. A capping member for sealing the nozzle formation face has an inner space formed with a bottom. An ink absorbing member is provided on the bottom of the inner space. In a first flushing mode, ink drops are ejected into the capping member in a state that the nozzle formation face is sealed by the capping member. In a second flushing mode, ink drops are ejected into the capping member in a state that the capping member is separated from the nozzle formation face. Either the first flushing mode or the second flushing mode is selectively performed.
