Problems solved by technology

[0006] However, the printing apparatus described in Patent Document 1 adjusts the ejection timing of ejected droplets only in two classifications of images with large dots and images other than large dots.
Therefore, the effect of correcting the landing position deviation of the liquid droplets ejected when moving outward and the liquid droplets ejected when moving inward, and the effect of suppressing the decrease in printing quality due to the deviation of the landing position are low.

Embodiment approach

[0030] Outline configuration of printing device

[0031] figure 1 It is a schematic diagram showing a schematic overall configuration of the printing apparatus according to the embodiment. First, refer to figure 1 , the schematic configuration of the printing apparatus 100 according to this embodiment will be described. In addition, in this embodiment, the inkjet type printing apparatus 100 which performs printing on the recording medium 95 by forming an image etc. on the recording medium 95 is taken as an example and demonstrated.

[0032] Such as figure 1 As shown, the printing device 100 includes: a medium conveying unit 20 , a medium adhering unit 60 , a printing unit 40 , a drying unit 27 , a cleaning unit 50 , and the like. Furthermore, it has the control part 1 which controls each said part. Each part of the printing device 100 is attached to the frame part 90 . In addition, the printing apparatus 100 has an image processing apparatus 110 (refer to image 3 ).

Abstract

A printing apparatus includes a medium transport portion configured to transport a recording medium in a transport direction, a discharge head configured to discharge liquid droplets each having one size among mutually different sizes onto the recording medium, a head moving portion configured to reciprocate the discharge head in a main scanning direction intersecting with the transport direction, a printer controller serving as a calculation portion configured to analyze the size of each of the liquid droplets and quantities with respect to the liquid droplets on the basis of image data corresponding to an image to be printed on the recording medium to calculate at least one adjustment value to be applied to discharge timing points at each of which a corresponding one of the liquid droplets is discharged, and a controller configured to change the discharge timing points on the basis of the at least one adjustment value.

Description

technical field [0001] The invention relates to a printing device and a printing method. Background technique [0002] Conventionally, there is known an inkjet type printing apparatus that forms an image or the like by reciprocating a head that ejects liquid droplets (ink droplets) for forming dots of different sizes along the width direction of a recording medium. on the recording medium. Droplets ejected from the nozzle have different landing positions on the recording medium due to their size (mass), so when a droplet larger or smaller than a predetermined size is ejected, it will cause the liquid to move outward and inward. The landing position of the droplet is deviated. For example, Patent Document 1 discloses a printing apparatus that classifies printed images into large-dot images such as barcodes that are printed using large-size dots in most cases, and images other than large-dot images, and uses The adjustment value of the image landing position deviation is us...
