Gravure connection line snowflake technology and curing system thereof

Abstract

The invention discloses a gravure connection line snowflake technology and a curing system of the gravure connection line snowflake technology, and belongs to the technical field of gravure. The technology comprises the steps that 1, a gravure press is adopted, UV snowflake ink and laser engraving gravure with the depth of 60-70 micrometers are adopted for printing; and 2, the printed UV snowflakeink is wrinkled and dried, the paper path distance between a wrinkling lamp box for wrinkling and a drying lamp box for drying is 2-3 m. The curing system comprises a color class, the drying lamp boxarranged on one side of the color class, a color supporting frame arranged above the color class, and the wrinkling lamp box arranged on the side, opposite to the drying lamp box, of the paper supporting frame. The snowflake technology on the gravure press can be achieved with high efficiency and high quality, and therefore the production efficiency is greatly improved.

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.
