Description
Technical field
The present invention relates to a kind of three-dimensional bronzing method, relate in particular to a kind of high-gloss three-dimensional gilding method that high-efficiency and continuous that oiliness UV printing ink is process materials produces of take.
Background technology
In recent years, along with the raising of people to commodity packaging overall styling and quality requirement, printing technology, packing technique all make great progress, and the post-press finishing technology has obtained vigorous growth especially, and electrochemical aluminium thermoprinting is as the part of post-press finishing, the variation in these several years is huge especially.The continuous appearance that new technology, new technology and multiple technologies are combined with, make package printed matter all obtain effect preferably on glossiness, third dimension, metal sense, anti-counterfeiting performance after gold stamping, especially at present application is three-dimensional thermoprint technology more and more widely, makes the packing of commodity seem high-grade exquisite, splendid and be rich in individual character.
The existing method that makes pattern on paper have stereoeffect, include three-dimensional bronzing method, its normally first to paper treat gold stamping pattern position carry out gold stamping, then this gold stamping position is hit protruding, the pattern that there is stereoeffect with formation.Yet, because paper has certain receipts of stretching, the base portion that hits the protuberance position is difficult to form pattern, again because the thinner paper of general thickness is all soft, hit protruding part and be easy to compressive deformation, therefore, the space pattern of gold stamping formation is difficult to the long-term stereoeffect that keeps.
ZL200910190392.1 discloses a kind of three-dimensional bronzing method, and its gold stamping slurry adopted is the water-based rubber cement, after silk-screen, needs just can carry out after air-dry after a while gold stamping, and the required process time is longer, is unfavorable for realizing that efficient line is gold stamping; And because its gold stamping slurry adopted is the water-based rubber cement, not strong with base material adhesive force, so this bronzing method can not apply on the printed sheet of laminating optical cement, mute glue and the impermeabilisation enclosed type base materials such as plastic sheet and fibrous plate, the applicability deficiency; Easily produce after another this bronzing method silk-screen that air spots, bubble form that pore is many, the defects such as scumming and stroke lines,
Summary of the invention
The object of the present invention is to provide a kind of high-gloss three-dimensional gilding method, adopting oiliness UV printing ink is gold stamping slurry, after silk-screen, the surperficial levelability of gold stamping slurry is better, after the UV photocuring, can carry out gold stampingly, gold stamping pattern glossiness is high, remarkably productive, and can realize that high-efficiency and continuous is gold stamping, produce fast, steady quality, can meet the diversified demand of processing base material.
For achieving the above object, the invention provides a kind of high-gloss three-dimensional gilding method, comprise the following steps:
