New process for realizing inline positioning and cold stamping of intaglio printing and transferring of positioned C2

Abstract

The invention relates to a new process for realizing inline positioning and cold stamping of intaglio printing and the transferring of a positioned C2, which comprises the following steps: a. rolling paper is placed into a unwinding device of a printing machine; b. the rolling paper is pulled to a discharging pull roll; c. afterwards, the paper moves into a first printing color unit for printing pattern; d. after being printed by the first printing color unit, the paper moves into a cold stamping unit, a transfer layer on a transfer film arranged in the cold stamping unit is positioned on the paper by the cold stamping; e. the paper moves into a multicolor printing color unit for printing pattern; f. after being subject to printing the pattern by the multicolor printing color unit, the paper moves into another positioning and cold stamping unit to enable other patterns to be positioned by the cold stamping; g. the paper moves into a C2 transferring unit for positioning and transferring, so that the convex and concave patterns on the transfer film are reflected on the paper coated with UV glue, and then, a procedure of cured stripping or stripping prior to curing should be carried out by using composite materials; and h. the stripped paper is cut off by a cutting device to finish the whole process.

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 the realization of gravure printing on-line positioning cold ironing and positioning C 2 New process for transfer. 【Background technique】 [0002] In the packaging and printing industry, cold stamping printing technology provides new opportunities for printing companies. Compared with blanching, its biggest advantage is less investment, simple structure, easy operation, and high cost performance. In addition, because cold stamping technology does not need to make expensive hot stamping plates, it is very suitable for short-run, low-quality labels and proofing production. while C 2 It is a better process than cold perm transfer technology, C 2 The transfer film used does not have a transfer layer, and the transfer material can be reused many times, thereby further saving the cos...

Problems solved by technology

[0003] However, due to technological reasons, the finishing of domestic and foreign packaging products is done after printing, off-line cold ironing transfer, off-line C 2 Therefore, there are the following problems: first, there are many production lines and low production efficiency; second, there are many product processes, difficult quality control, high product consumption, and high scrap rate; third, poor product accuracy
