Gravure connection line snowflake technology and curing system thereof

Abstract

A gravure printing connecting line snowflake process and its curing system belong to the technical field of gravure printing. The process of the present invention comprises the following steps: step 1, adopting a gravure printing machine, UV snowflake ink and a laser engraved gravure with a plate depth between 60-70 microns to print; step 2, printing the printed UV snowflake ink through a UV curing system Carry out wrinkling and drying, wherein the paper path distance between the wrinkling light box for wrinkling and the drying light box for drying is 2-3 meters. The curing system of the present invention includes a color group, a drying light box arranged on one side of the color group, a paper support frame arranged above the color group, and a wrinkle light box arranged on the opposite side of the paper support frame and the drying light box . The invention can realize the snowflake process on the gravure printing machine with high efficiency and high quality, so as to greatly improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of gravure printing, in particular to a gravure printing connecting snowflake process and a curing system thereof. Background technique [0002] At present, with the development of the design process of cigarette packaging material products, silk screen printing processes are increasing, such as refraction, snowflakes, fission, etc., resulting in the problem of low efficiency of screen printing equipment. From the perspective of equipment efficiency and production guarantee, the manufacturing of screen printing products has increasingly become the company's production bottleneck, restricting production scheduling and delivery cycle. It mainly has the following defects: 1. The printing efficiency is low, and the screen printing speed is generally 2500-3000 sheets / hour, which is far from the gravure printing speed; There is instability. If the deformation is serious or the screen is broken, it will also have ...

Problems solved by technology

It mainly has the following defects: 1. The printing efficiency is low, and the screen printing speed is generally 2500-3000 sheets / hour, which is far from the gravure printing speed; There is instability. If the deformation is serious or the screen is broken, it will also have a great impact on the quality and efficiency of the printed matter; 3. Compared with the ink blooming effect of the printing quality, the gravure printing is relatively stable compared with the silk printing

[0003] Therefore, gravure printing has great advantages over silk screen printing, but there are still difficulties in realizing snowflakes and other processes on gravure printing machines: due to the particularity of silk screen printing snowflakes, it is necessary to fully induce wrinkles and dry twice in a short period of time. However, the speed of the existing gravure printing machine is relatively fast, which cannot guarantee sufficient wrinkles. The existing method is generally to reduce the speed appropriately, and continuous printing is not possible.
