A recording device includes: a first nozzle group including a plurality of nozzles configured to discharge, to a medium, a first dot that is a dot of a reaction liquid; a second nozzle group including a plurality of nozzles configured to discharge, to the medium to which the reaction liquid is discharged, a second dot that is a dot of ink containing a color material that coagulates with the reaction liquid; and a control unit configured to control discharging of the first dot by the first nozzle group and discharging of the second dot by the second nozzle group, in which the control unit controls arrangement, on the medium, of the first dot discharged by the first nozzle group so as to be more regular than arrangement, on the medium, of the second dot discharged by the second nozzle group.

Recording device and recording method for discharging ink and reaction liquid

Provided is a printing method for forming ink dots on a printing medium by using a plurality of nozzle rows that discharge a plurality of types of photocurable inks. The printing method includes detecting a defective nozzle that has an ink discharge fault, and compensating for dot omission by causing, preceding the defective nozzle, a preceding nozzle that discharges an inducing ink different from a compensation target ink, which the defective nozzle should have discharged, to discharge the inducing ink to a position on the printing medium where dot omission occur due to the defective nozzle.

An image processing apparatus configured to generate, based on image data corresponding to a printing image, print data for causing a printer to execute printing includes an input unit (input device, display device) configured to receive, for each of the first ink and the second ink, an ink discharge correction volume for correcting an ink volume discharged from predetermined nozzles among a plurality of first nozzles and a plurality of second nozzles, and a print data generating unit (printer driver) configured to generate the print data based on the image data and the ink discharge correction volume input.

When the discharge volume of a specific ink is adjusted additionally to uniformly adjusting the discharge volume of a plurality of inks used for printing, a correction ratio input unit of a printer driver execution unit of a print control device receives input of a total correction ratio for correcting the discharge volume of cyan ink, magenta ink, yellow ink, and black ink, and receives input of a specific correction ratio for further correcting the discharge volume of black ink. The discharge volume correction unit sets the corrected discharge volume of cyan ink, magenta ink, and yellow ink to the product of the rated discharge volume times the total correction ratio, and sets the corrected discharge volume of black ink to the product of the rated discharge volume times a correction ratio multiple, which is the product of the total correction ratio and the specific correction ratio.

Print control device, control method of a positioning data, and positioning system

To minimize any decrease in image quality, even in an instance in which there is a displacement in a landing position of a fluid in a region in which nozzle rows overlap, (A) a fluid-ejecting device including: a first nozzle column; (B) a second nozzle column, the second nozzle column being arranged so as to form an overlapping region; and (C) a control part for causing the fluid to be ejected so that in each of a plurality of raster lines arranged in a row in the predetermined direction in the overlapping region, dots to be formed are apportioned between the first nozzles and the second nozzles; the control part causing the fluid to be ejected so that there are produced.
