Description

  The present invention relates to a method for forming an irregular transparent matte particle surface by a UV inkjet printer and a finished printed product thereof, and more particularly to using a transparent ink on a pattern layer of a substrate, The present invention relates to a method for forming eraser particles and a finished printed product thereof.

  UV inkjet printers can perform printing on printed materials of various materials or thicknesses, have high printing speeds, and can be printed stably and uniformly. It is highly competitive because it saves the process and production time and prints quickly and can provide an economical and practical printing method with a UV inkjet printer.

  Currently, commercially available UV inkjet printers are provided with an inkjet module that reciprocates under control on a sliding platform of the apparatus. The ink jet module is provided with a plurality of ink cartridges on the upper side, a plurality of nozzle heads for each ink cartridge corresponding to the lower side, and ink is ejected onto the substrate via the nozzles provided at the bottom of the nozzle head. After that, ultraviolet rays are applied to the ink on the printed material from a UV lamp provided on the side surface of the inkjet module, and the ink is rapidly cured and solidified. When printing a printing material, in the prior art, printing is performed in a single direction and a single time on each printing region of the printing material, or printing is performed by a bidirectional printing method that reciprocates in both directions, thereby shortening the printing time. In order to obtain a transparent matte effect after printing on the surface of the substrate, generally, after printing the pattern of each printing area of the substrate, a specific matting effect pattern is printed on the pattern of the printing area by a UV inkjet printer. Then, a single layer of transparent ink is ejected, and the transparent ink ejected onto the printing area is cured by a UV lamp to form a transparent layer on the pattern of the printing area.

  However, when printing is completed, the special effect of transparent matting is obtained on the surface of the above-mentioned printed material. However, UV inkjet printers are jetted onto each printed region of the printed material at different timings, so they are adjacent to each other. The connection location between the printed areas is shifted, the line is interrupted or the brightness of the reflected light becomes non-uniform, and the print quality may be deteriorated.

In order to solve the above-mentioned problems of the prior art, the surface of the irregular transparent matte particles is printed on the surface of the substrate after printing by the method of forming the irregular transparent matte particle surface with a UV inkjet printer. There has been a demand for a technique for obtaining a special irregular block-like matting effect by forming a layer and solving the problem of unevenness in the brightness of the light that is shifted or reflected from the connection portion.
Conventionally, as a recording method of a UV ink jet printer capable of forming an image having excellent glossiness free from unnaturalness, for example, there is one disclosed in Patent Document 1.
