Abstract

The invention relates to a gravure printing method using water-based ink. Water-based ink is printed on a printing substrate by a gravure printing machine. The gravure printing method comprises the following steps: preparation of the water-based ink, printing, drying, and winding. The gravure printing method has the advantages that the water-based ink is prepared by mixing isopropanol, n-propanol,ethanol, pigment, polyurethane resin and water, because the solvent component is water, the exhaust gas in the printing process can be directly discharged, the waste water treatment is relatively simple, and easier and less toxic than the hazardous solid waste treatment of solvent-based ink, for the improvement of the entire production process and social environment, the water-based ink is more environmentally friendly than the solvent-based ink, and volatile organic solvents are not contained, so that the working environment is improved, toxic and harmful substances in the solvent-based inkare eliminated, and the pollution of packaged goods is avoided.

Description

technical field [0001] The invention relates to a gravure printing method using water-based ink. Background technique [0002] Gravure printing is one of the four major printing methods, which directly imprints the ink contained in the gravure pits onto the substrate; gravure ink, also known as gravure ink, is a variety of gravure printing methods used The general term for ink. At present, in the printing process of the flexible packaging industry, organic solvent-based inks are mainly used. Due to the high speed of gravure printing, highly volatile inks must be used to meet the printing requirements, but at the same time a large amount of polluting gas is released. Moreover, the volatilization of this gas will cause physical damage to the on-site operators, which is the most polluting process, and the flammable and explosive characteristics of organic solvents can also easily lead to fire hazards. Contents of the invention [0003] The object to be achieved by the presen...
