Problems solved by technology

[0004] The finished flexible packaging printed by the existing gravure printing process for flexible packaging is prone to knife lines. The appearance of knife lines is generally related to the particle size of the ink particles and the viscosity of the ink. At the same time, it is easy to The ink is not firmly adhered to the substrate and peels off. In the gravure printing process, any deviation in any step will cause defects in the finished product

Abstract

The invention provides a gravure printing process for flexible packaging. The gravure printing process includes the following steps of manuscript design and manuscript reviewing, gravure printing plate making, material preparation, ink preparing, corona treatment, pretreatment, try printing, formal printing, drying treatment, defective product screening, compound treatment, curing treatment, cutting and bag making. According to the gravure printing process for flexible packaging, the particle size of ink particles made by ultrasonic dispersion treatment is uniform, the ink viscosity is moderate, thus the probability of a cutter line appearing in printed flexible packaging finished products is reduced, and the qualified rate and printing efficiency of the flexible packaging finished products are improved; an adhesive remover in ink compositions can reduce ink adhesion while not affecting the mobility of ink, thus the coloring rate of printing is improved, and the printed flexible packaging finished products have high quality; and through a drying inhibitor in the ink compositions, the phenomenon that the ink in the printing process dries too fast and consequently the ink on a printed material is peeled and skinned can be prevented.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a gravure printing process for flexible packaging. Background technique [0002] Flexible packaging refers to packaging in which the shape of the container can change after filling or removing the contents. Various bags, boxes, sleeves, packages, etc. made of paper, aluminum foil, fiber, plastic film and their composites are flexible packaging. [0003] Gravure printing, referred to as gravure printing, is one of the four major printing methods. As a printing process, gravure printing has thick ink layers, bright colors, high saturation, high printing plate durability, and The advantages of stable product quality and fast printing speed occupy an extremely important position in the field of printing, packaging and graphic publishing. [0004] The finished flexible packaging printed by the existing gravure printing process for flexible packaging is prone to knife lines. The app...
