Problems solved by technology

Similarly, if the UV irradiation device and the inkjet print head move relative to each other along the X—Y direction above the medium loaded on the drum, then the moving device of the UV irradiation device becomes a large-scale device that consumes a large amount of power.

Embodiment Construction

[0027] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

[0028] Figure 1 to Figure 3 In , the best embodiment of the inkjet printer of the present invention is shown.

[0029] expressed in figure 1 and figure 2 The structure of the printer in is: the inkjet print head 30 moves relatively above the medium 50 loaded on the drum 20 along the XY (vertical and horizontal) direction approximately parallel to the surface of the drum 20, and is irradiated by UV light. The device 60 irradiates ultraviolet rays to the UV ink droplets ejected from the nozzles 32 arranged below the inkjet printing head 30 and attached to the surface of the medium 50, so that the UV ink droplets are cured on the surface of the medium 50, so that the UV ink droplets can be cured on the surface of the medium 50 On the surface of the medium 50, images and / or texts composed of a plurality of UV ink dot arrays are printed.

Abstract

PROBLEM TO BE SOLVED: To provide an ink-jet printer using a UV ink which can greatly suppress a power consuming energy of a UV irradiation means, can make a UV irradiation means small, light-weight and simple, and can eliminate ozone generation at the time of illuminating a UV irradiation means.

SOLUTION: For the UV irradiation means which irradiates ultraviolet rays to UV ink droplets jetted from an ink-jet head of the ink-jet printer and placed on a printing medium surface carried on a platen, thereby hardening the ink droplets, a UVLED or an array unit of UVLEDs is used which has no waiting time at the illuminating time, generates no ozone at the illuminating time and less consumes the power consuming energy.

Description

technical field [0001] The present invention relates to an inkjet printer using UV ink of the type that ejects droplets of ultraviolet curing type UV ink (ink cured by irradiating ultraviolet rays) from an inkjet print head. Background technique [0002] Known inkjet printer is as follows: from the nozzle that is arranged on the inkjet printing head below ejects ultraviolet curable type UV ink drop to medium surface, and nozzle is along the X—Y (longitudinal and horizontal direction) direction that is roughly parallel with cylinder surface, is loaded on cylinder Relatively move above the printing medium (recording medium, hereinafter referred to as the medium) on the printing surface. [0003] This printer includes a UV irradiation device that irradiates ultraviolet rays to UV ink droplets ejected from the inkjet print head and adhered to the surface of the medium to cure the UV ink droplets. Then, the UV irradiation device irradiates ultraviolet rays to the UV ink droplets...
