no. 1 approach

[0065] The printer 1 of the first embodiment is capable of ejecting color inks of four colors (yellow ink Y, magenta ink M, cyan ink C, and black ink K) and transparent colorless ink CL. These inks used in the first embodiment are UV inks (ultraviolet curable inks).

[0066] figure 1 It is a schematic side view of the printer 1 of the first embodiment. figure 2 It is a schematic plan view of the printer 1 of the first embodiment. image 3 is a block diagram of the printer 1 in the first embodiment. Hereinafter, the configuration of the printer 1 will be described with reference to these figures.

[0067] image 3 A printer 1 and a computer 110 are shown in . The printer 1 has a paper conveyance unit 10 , a head unit 40 , a detector group 50 , a controller 60 , a drive signal generation circuit 70 , a temporary curing unit 80 , and a final curing unit 90 .

[0068] The paper transport unit 10 includes: a transport roller 11A, a first pressing roller 11B, a paper discharg...

no. 2 approach

[0113] Figure 13 It is a schematic side view of the printer 1 of the second embodiment. Figure 14 It is a schematic plan view of the printer 1 of the second embodiment. In the second embodiment, the configuration other than the head unit 40 of the first embodiment is substantially the same. Here, in the second embodiment, 100 is added to the symbols of the first embodiment, and the description of the same configuration is omitted. Furthermore, the configuration of the head unit which is different from that of the first embodiment will be described.

[0114] In the second embodiment, the order of ink ejected by the heads of the respective head units is different from that of the first embodiment. In the second embodiment, the head unit 141-1 ejects yellow ink and magenta ink. In addition, the head unit 141-3 also ejects yellow ink and magenta ink. The head unit 141-2 ejects cyan ink and black ink. In addition, the head unit 141-4 also ejects cyan ink and black ink. Als...

Embodiment approach

[0122] In the above-mentioned embodiment, the printer 1 was described as the liquid discharge device, but it is not limited to this, and it can also be embodied as a fluid (liquid and / or liquid body in which fine particles of functional materials are dispersed) other than ink. , colloid-like fluid) liquid discharge device. For example, color filter manufacturing equipment, dyeing equipment, microfabrication equipment, semiconductor manufacturing equipment, surface processing equipment, three-dimensional molding machines, gas vaporization equipment, organic EL manufacturing equipment (especially polymer EL manufacturing equipment), display manufacturing equipment, The same technology as that of the above-described embodiment can also be applied to various devices using inkjet technology, such as a film forming device and a DNA chip manufacturing device. In addition, these methods and / or manufacturing methods are also within the category of the scope of application.

Abstract

To reduce the tendency of glossiness to vary according to the ink ejection quantity, a printing device includes a color ink head for ejecting color ink to a medium, a clear ink head for ejecting transparent clear ink to the medium, and a controller for controlling ejection of the clear ink so that the clear ink is ejected to a region in which an ejection quantity of the color ink per unit area of the medium is less than a predetermined quantity, and the clear ink is not ejected to a region in which the ejection quantity of the color ink per unit area of the medium is greater than the predetermined quantity.

Description

technical field [0001] The invention relates to a printing device and a printing method. Background technique [0002] A printing apparatus using ultraviolet curable ink (hereinafter referred to as "UV ink") that is cured by irradiating ultraviolet rays has been developed. In addition, a printing device has been developed that provides glossy printed matter by coating with transparent ink in printing with UV ink. [0003] Patent Document 1 discloses an image recording system that uses two types of transparent inks to provide a matte-feeling print and a glossy print. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2006-88529 [0005] During image formation, the degree of reflection of light with respect to ink changes according to the amount of ink attached. For example, when the amount of ink attached is large, adjacent inks are integrated due to surface tension, and incident light is reflected at approximately the same angle, thereby providing a printed matter ...
