Abstract

The invention discloses a method for laser imprinting transfer on wrapping paper. The main techniques of the method comprise the following steps: A. UV oil is pre-coated on the paper by a screen printing method; namely in printing, the UV oil is poured into one end of a screen printing plate, a scraper blade exerts certain pressure in the UV oil position on the screen printing plate, and at the same time the UV oil moves to the other end of the screen printing plate; the UV oil is extruded on the paper by the scraper blade from parts of oil penetrating meshes in moving; B. the coating surface of a laser film is touched with the UV oil surface on the paper, and the UV oil is stuck to the surface of the laser film with the laser coating; C. the irradiation of a UV light solidifies the UV oil; D. the laser film is stripped; and E. the dried UV oil of the laser coating on the laser film completes laser transfer on the paper. In order to overcome the defects of bad coating quality, insufficient overprinting precision and limited coating amount of the existing method for laser imprinting transfer, the invention provides the method for laser imprinting transfer with thick UV oil layer and high precision.

Description

【Technical field】

[0001] The invention relates to a laser embossing transfer method on wrapping paper. 【Background technique】

[0002] In order to make the packaging paper of cigarette boxes, toothbrush boxes, packaging boxes, book covers, etc. beautiful, the laser coating on the laser film is often transferred and embossed on the packaging paper, so that the packaging paper has a laser effect and is radiant. While highlighting the theme of the layout, it also improves the surface decoration effect of the printed matter, so as to achieve the purpose of making the printed matter even better.

[0003] In order to make the laser coating on the laser film adhere to the wrapping paper, it is necessary to pre-coat the paper with UV oil. In the prior art, a partial UV machine is generally used for coating. Partial UV machine coating, using UV oil with high brightness, transparency and wear resistance, UV oil is stuck on the coating roller, and the coating roller rotates to coat th...
