Problems solved by technology

[0008] Furthermore, in the above-mentioned earnest study, regarding the printing results of each main scanning operation (each printing pass) of the multi-pass method, it was found that the printing quality varies depending on the printing pass.
In addition, through further careful study, it was found that, for the difference in printing quality, more specifically, for example, the spread of ink dots formed on the medium (dot gain) etc., that in the printing path There is a difference between them, and there is an imbalance between the printing paths, etc.
Additionally, for differences in dot gain, it was found that this occurs within a print pass as well

Embodiment Construction

[0064] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example of the configuration of a printing device 10 according to an embodiment of the present invention. FIG. 1( a ) shows an example of the configuration of the main part of the printing device 10 .

[0065] In addition, the printing device 10 may include, for example, the same or similar configuration as a well-known inkjet printer, in addition to the configuration of the main part shown in FIG. 1( a ). For example, the printing device 10 of this example may have the same or similar configuration as a JFX500 flatbed ultraviolet (Ultraviolet, UV) printing machine manufactured by Mimaki Engineering Co., Ltd., except for the points described below.

[0066] In this example, the printing device 10 is a platform-type inkjet printer, and also includes an inkjet head 12, the first ultraviolet light source 14, a scanning drive unit 16, the second ultraviolet l...

Abstract

A printing apparatus, including: an ink jet head for ejecting ink droplets of an ultraviolet curing type ink toward a medium; a temporary curing ultraviolet light source; an irradiation setting storage section which stores ultraviolet irradiation settings of ultraviolet rays from the temporary curing ultraviolet light source to the medium; and a curing completion ultraviolet light source being for completing curing of the dots of the ink, is provided. The ink jet head performs a printing by a multi-pass method. The ultraviolet irradiation settings are set so that, regarding temperature of the region where the ink jet head ejects ink droplets in each main scanning operation in the multi-pass method, an increasing range of temperature compared with temperature at a timing of the last main scanning operation is suppressed within a temperature rising range which dot gains of the dots of the ink are substantially the same as each other.

Description

technical field [0001] The invention relates to a printing device and a printing method. Background technique [0002] Conventionally, ink jet printers (ink jet printers) that perform printing using ultraviolet curable inks (ink) have been widely used (for example, see Non-Patent Document 1). In such an inkjet printer, ink droplets are generally ejected from an inkjet head toward a medium, and the ink is cured by irradiating ultraviolet rays to ink dots formed by the ink droplets hitting the medium. In addition, in recent years, multipath printing in which the main scanning operation is performed multiple times for each position of the area to be printed has been widely performed due to the required improvement in printing resolution and printing quality.
