Description

UV printer system for metal

The present invention relates to a UV printing system for metal materials that can be used as a frame or finishing material for construction by printing in various colors such as wood wood color, marble color, natural scenery, and people on the surface of a metal plate.

In general, in order to form a three-dimensional effect and gloss on an ink print, a method of applying a gloss liquid, that is, a solution generally referred to as varnish, and curing it is used.

In this case, technologies including a curing device such as printers, printing machines, etc. have been proposed so that the varnish can be cured at the same time as applying the varnish without going through a separate curing process.

As such a prior art, there is Registration Patent No. 10-1000381, 『Inkjet Printer and Printing Method』, in which the conventional technology temporarily cures the UV ink attached to the printing medium by irradiating ultraviolet rays toward the printing medium supported by the support table. A controller that controls the amount of ultraviolet rays irradiated by the UVLED unit and the UV ink attached to the print medium by the UVLED unit from the amount of light to temporarily cure the UV ink to the amount of light to be cured. Presents an inkjet printer and printing method equipped with a control unit that can switch between the two-stage curing mode, which temporarily cures the attached UV ink and then cures the main cure, and the first-stage curing mode, which cures the UV ink by a single UV irradiation. Are doing.

In addition, as a prior art, there is Patent Publication No. 10-2006-0009021 “Inkjet Printer Using UV Ink”, which is applied to UV ink droplets sprayed from the inkjet head and hit the surface of the printer media mounted on the platen. By using a UVLED or UVLED array unit as a UV light emitter of a UV irradiation means that cures the ink droplets by irradiating UV rays, the power consumption energy of the UV irradiation means can be significantly suppressed, and the size and weight of the UV irradiation means can be simplified and simplified. It proposes an inkjet printer that uses UV inks.

Furthermore, as a prior art, there is Registration Patent No. 10-1081711, 『Ink curing device for UV label printers』, which is a guide arranged parallel to the rear side of the conveying direction of the printing paper for labels rather than the head part of the housing of the UV label printer. An ink curing apparatus for a UV label printer comprising a curing unit movably installed on a rod and a driving device installed on the housing to displace the curing unit with respect to the head unit is provided.

In addition, as a prior art, there is a registered patent No. 10-0422405 "Inkjet device having an instant curing function". The prior art includes an inkjet material transfer support part for transferring the main body and the inkjet material, and a feeding device for the inkjet material after printing. In the inkjet printer described above, a technology including a head for printing by spraying ink onto an inkjet material, and an ultraviolet exposure apparatus for immediately curing the jetted ink by being attached to one or both sides of the head is provided.

However, the prior art is a device for curing ink or UV ink, and in the case of applying a varnish (varnish) to improve the quality of printed matter, the surface is not smooth or a layer is formed inside according to the curing method and process. Defects such as, etc. may occur, and problems such as varnish flowing down may occur depending on the degree of curing.
