摘要： Provided is a printing method for performing printing using a serial printer. In printing of a print image including a line image, the printing method includes a raster line forming step of forming each of raster lines configuring the image, by a plurality of pass operations. In the formation of each of the raster lines, when printing of a region corresponding to edge pixels of the line image by a first pass operation, which is one of the plurality of pass operations, is first printing, and printing of the region corresponding to the edge pixels by a second pass operation that is different from the first pass operation, of the plurality of pass operations, is second printing, a brightness of the printing by the second printing is higher than a brightness of the printing by the first printing.

摘要： An image processing method of generating print data to cause a printing system (printing apparatus) that prints a print image based on image data to execute printing, by repeating a pass operation in which nozzle arrays form dots on a printing medium by while moving relative to the printing medium in an X-axis direction (main scanning direction), and a feed operation in which the nozzle arrays and the printing medium are moved relative to each other in a subscanning direction that intersects with the X-axis direction (main scanning direction) includes: performing multiple halftone processes (first and second halftone processes) for a same region of image data, the halftone processes being to generate halftone data to determine a formation state of dots formed by each nozzle array that ejects a same color of ink; and allocating the generated halftone data to the pass operations.

摘要： A liquid ejecting apparatus includes a head in which a first nozzle group, a second nozzle group, and a third nozzle group which have a plurality of nozzles are disposed in a predetermined direction, and that can eject a liquid on a medium, a main scanning unit that scans the head in a main scanning direction, a sub scanning unit that relatively moves between the head and the medium in a sub scanning direction intersecting the main scanning direction; and a control unit. When the liquid is ejected to form a plurality of raster lines on the medium, the control unit maintains fixed values for each total value of a nozzle usage rate of the first nozzle group, total value of a nozzle usage rate of the second nozzle group, and total value of a nozzle usage rate of the third nozzle group, corresponding to the respective raster lines.
