Method for realizing multi-color-class positioning cold wave transfer printing

Abstract

The invention provides a method for realizing multicolor set location cold waving transfer printing, which is suitable for gravure printing, flexographic printing and offset printing. The method comprises the following steps: a. drum paper is firstly put into the unreeling device (1) of a printing machine; b. the drum paper is secondly pulled out to be towed to a feeding drawing roller (2); c. the paper (5) going out from the feeding drawing roller (2) enters a first printing color set (3) to carry out pattern printing; d. after the first printing color set (3) carries out the printing, the paper (5) enters a cold waving transfer unit (7), and a transfer film (6) arranged in the cold waving transfer unit (7) is transferred onto the paper (5) in an overprinting way; e. after the cold waving transfer unit (7) carries out overprint, multi-set printing color set (8) carries out the printing; f. the drum paper which completes the printing goes to a discharging drawing roller (9) to carry out drawing; and g. finally, the drum paper reaches a reeling device (10) to complete location cold waving printing.

Description

【Technical field】 [0001] The invention relates to the technical field of printing and packaging applied to cigarette packaging boxes, alcohol and high-grade gift paper, and specifically relates to a method capable of realizing high-precision, high-speed multi-color group positioning and cold ironing transfer. 【Background technique】 [0002] In the packaging and printing industry, in order to pursue high-end and luxurious packaging products, anodized aluminum embellishes the surface of printed matter with its magnificent, exquisite and elegant decoration, enhances the artistry of printed matter, and plays a prominent role in promoting the theme; its brightness is greatly improved. Exceeding gold and silver printing, the product has a high-end feeling and gives people a beautiful enjoyment. At the same time, due to the excellent physical and chemical properties of anodized aluminum, it plays a role in protecting printed products, so a large number of hot stamping processes will...

AI Technical Summary

Problems solved by technology

Hot stamping products use hot melt adhesive to melt and transfer the anodized aluminum layer to the paper under heating. Due to the constraints of hot melt adhesive, hot stamping template, heating temperature and other factors, the production speed of hot stamping process is limited, generally not exceeding 60 m / min; due to the high temperature of the hot stamping process, it is difficult to transfer large areas of hot stamping. Due to the above reasons, hot stamping transfer is difficult to carry out in-line hot stamping; and hot stamping transfer process is impossible to perform half-tone due to the limitation of the process layer transfer printing

[0003] Due to technological reasons, the domestic and foreign finishing of packaging products today is done by hot stamping transfer after printing and off-line processing, so there will be the following problems: first, the production efficiency is low; second, the process of the product Many, difficult quality control, high product consumption; third, poor registration accuracy; fourth, halftone level transfer and online printing after transfer cannot be performed
