摘要： A printing device includes a plurality of heads, a movement mechanism, and a calculation unit. The heads are configured to print an image on a medium by discharging colored inks onto the medium. The heads discharge the inks at different positions in a predetermined direction. The movement mechanism is configured to move the medium and the heads in the predetermined direction relative to each other. The calculation unit is configured to determine respective discharge amounts of ink discharged from each of the heads when the image is printed. A position in the predetermined direction, in which the inks are discharged from the heads, is varied based on the discharge amounts determined by the calculation unit.

摘要： For each of a plurality of reference colors located at prescribed coordinates in a first color space (e.g., the RGB color space), there are associated, on an individual pixel row basis, correction vectors indicating correction amounts in the first color space. For each pixel datum of image data of first tone values (e.g., 256 tone values) of the first color space prior to a color conversion process, a correction process is carried out on the basis of the correction vector that has been associated with the pixel row to which a given pixel belongs, the correction vector also being associated with the reference color of a location surrounding the coordinates that indicate the pixel data in the first color space. The color conversion process and the halftoning process are carried out on image data composed of the pixel data that has been subjected to the correction process.

摘要： A test pattern is formed by forming a plurality of dot rows using a first printing in a first printing region and a second printing region, transporting a medium by a predetermined transport amount, and forming a plurality of dot rows using a second printing in the second printing region. Second printing region correction values are obtained based on a reading result of a scanner. Densities of a print image constituted by a plurality of dot rows of the second printing region are corrected by correcting data corresponding to the second printing region correction values based on the second printing region correction values. In such a printing method, when forming the print image, if a transport amount of transport to be carried out between the first printing and the second printing is set shorter than the predetermined transport amount, data corresponding to a portion of correction values of the plurality of second printing region correction values is not corrected based on the portion of the correction values.

摘要： A printing method includes by printing a first area in a test pattern using a first print mode, determining a first correction value corresponding to the first print mode for each of the row regions, based on a density measurement value for each of row regions in the first area, by printing a second area in the test pattern using a second print mode for a plurality of cycles of periods that is determined by a combination of the row region and the nozzle, determining a second correction value corresponding to the second print mode for each of the row regions, based on a density measurement value for each of the row regions in the second area, and in a coexistent segment in which certain row regions and other row regions are mixed, correcting an ink ejection amount in each of the row regions using a combined correction value that is obtained as a composition of the first correction value and the second correction value. The first print mode is a print mode applied to an end area of a medium in a transport direction, and involves repetitively carrying out a movement-and-ejection operation of ejecting ink while moving nozzles in a movement direction that intersects the transport direction and a first transport operation of transporting the medium in the transport direction by a first transport amount. The row regions are a plurality of regions lined up in the transport direction and are each a region in which a dot row is formed along the movement direction by the movement-and-ejection operation. The first correction value is determined based on a value in which the first provisional correction value is multiplied by an attenuation coefficient. The first provisional correction value is determined for each row region based on a density measurement value of each of the row regions in the first area. The second print mode is a print mode applied to a middle area of the medium in the transport direction, and involves repetitively carrying out the movement-and-ejection operation and a second transport operation of transporting the medium in the transport direction by a second transport amount. The second correction value is determined based on a value in which the second provisional correction value is averaged. The second provisional correction value is determined for each of the row regions based on a density measurement value of each of the row regions in the second area. The certain row regions are each a row region in which the dot row is formed by the first print mode, and the other row regions are each a row region in which the dot row is formed by the second print mode.
