Abstract

The invention discloses a water-soluble ink printing process for woven bags. The water-soluble ink printing process includes plate making, ink blending, printing plate mounting, ink scraper mounting,positioning, ink application to a printing plate, debugging, printing, drying, and pulling and collecting. The water-soluble ink printing process has the advantages that intaglio printing is adopted,so that high printing speed, large printing quantity, rich printing hue and fine quality are achieved; the selected water-soluble waterproof printing ink for the woven bags is free from poison and irritating odor, has high printing adaptability and high glossiness, and is resistant to water, applicable to printing of the plastic woven bags for food, subsidiary agricultural products and the like, and harmless to human bodies.

Description

technical field [0001] The invention relates to the field of printing, in particular to a water-soluble ink printing process for woven bags. Background technique [0002] With the rapid development of society and technology, plastic woven bags have played an irreplaceable role in people's lives, but the common printing inks for plastic woven bags on the market are oily and purely soluble, and have solvents. The residual problem is harmful to the human body. At the same time, the common printing method of woven bags on the market is screen printing, which is only suitable for small batch printing, and it is prone to color registration or printing phenomenon during printing. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a water-soluble ink printing process for woven bags. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a water-soluble ink printing...
