Problems solved by technology

Using UV ink to print a large area of ​​sand surface effect will require an additional UV curing device during the production process, which is costly; the adhesion is poor, and a layer of UV primer must be applied before printing to increase the adhesion; UV ink is not dry It is irritating to the skin and respiratory tract before, and a certain odor will remain after curing, which will affect the health of the operator, and the resulting product does not have the performance of recyclable treatment.

Abstract

The invention provides a gravure water-based ink printing process ensuring a sand surface effect. The process comprises the following steps of: graving a gravure plate, controlling an ink cell opening of the gravure plate to range from 100 to 130mu m and the plate depth to range from 25 to 35mu m; blending water-based ink, namely selecting water-based ink which has the operating temperature of normal temperature and the grain size of less than 25mu m, and adjusting the viscosity of the water-based ink for 22 to 25 seconds (at 25DEG C) by using a solvent; printing; and drying a printed matter by adopting a hot air drying system, wherein the air speed of the hot air is 60-70m / s and the temperature of the hot air is 110-120DEG C. By the process, large-area high-precision printed matters with the sand surface effect can be obtained; and the obtained products have high printing quality and low cost, and are more easily recycled than products printed with ultraviolet (UV) ink, and the production process is safe and environment-friendly.

Description

technical field [0001] The present invention relates to a decorative printing process called sand surface effect, in particular to an environmentally friendly printing process using water-based ink printed with a gravure printing machine to obtain a large-area frosted effect. Background technique [0002] Sand surface effect printing is to print ink on the substrate with mirror gloss to form a rough surface like frosted glass with a certain feel. Among them, the most widely used and mature technology is the high-speed gravure sand surface effect printing process. Its principle and process are: with the help of a high-speed gravure printing machine, the ink is printed on the paper, and then the ink is dried by the equipment, leaving The ink particles on the paper present an effect similar to metal etching, but the high-speed gravure sand surface effect printing described in the prior art is only limited to the use of UV inks to achieve (see application number 200710052840.2, ...
