Problems solved by technology

The hot stamping process increases the production process, and the production efficiency is lower than that of the printing production. Moreover, the hot stamping process has higher requirements on the control of temperature and pressure. If the temperature and pressure are not well controlled, it will cause broken lines, paste, and serious expansion and deformation of the paper. , which results in low yield and high printing cost, which not only increases the difficulty of quality control, but also affects the quality of subsequent processes, etc.

Abstract

The invention provides silver ink with a good metal printing effect and a printing process using the silver ink. The printing process comprises the steps that first, a coated surface of a white cardboard with a single side coated is coated with water-soluble varnish or UV (ultraviolet) varnish, images and texts are printed with well mixed gravure silver ink in a gravure manner, and finally, a layer of water-soluble varnish or UV varnish is printed on an image and text area with the gravure silver ink. The gravure silver ink is formed by blending the following materials in percentage by weight: 60-68% of silver powder, 24-30% of n-propyl acetate, 1-3% of methyl methacylate, 1-3% of butyl acrylate, 1-2% of methacrylic acid, 1-2% of N-hydroxymethyl acrylamide, 0.5-1% of allyl methacrylate, 0.5-1% of isooctyl thioglycolate, 0.2-0.5% of alkylphenol ethoxylates sodium sulfate, 1-2% of water-resistant agents and 0.1-0.5% of drying agents. By means of the silver ink and the printing process, a metal ink layer has a refraction effect, the metal effect is more obvious and an optimal metal effect is achieved.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular to a silver ink with good metal printing effect and a printing process using the ink. Background technique [0002] With the development of the economy and the prosperity of the market, people have higher and higher requirements for commodity packaging. Metal effects such as gold and silver are used on many paper packages to beautify and enhance the grade of the product. [0003] Existing technology will realize metal effect on paper packaging material, and the one, is to use gold cardboard, and the 2nd, is to use bronzing process. The price of gold cardboard is high, resulting in high packaging costs. There are also many patterns that need to use a large amount of ink to cover the metal base, which causes a large amount of ink to be used, which increases the difficulty of printing production and increases the risk of VOC and other residuals. The hot stamping process u...
