Abstract

The invention discloses a single-concave embossed oil printing process, which comprises the following step of (1) manufacturing printing ink, wherein the printing ink is prepared from the following raw materials: 8 to 10 parts of UV highly branched polyester acrylic resin, 15 to 20 parts of polyamide resin, 2 to 5 parts of silane, 1 to 3 parts of titanate, 2 to 4 parts of potassium sorbate, 0.6 to 1.5 parts of antioxygen, 3 to 7 parts of dispersing agent, and 1.5 to 4.5 parts of defoaming agent. According to the single-concave embossed oil printing process provided by the invention, through arranging corona treatment, the tension of a printed material surface is improved, and a polar surface layer is formed; 8 to 10 parts of UV highly branched polyester acrylic resin, 15 to 20 parts of polyamide resin, 2 to 5 parts of silane, 1 to 3 parts of titanate, 2 to 4 parts of potassium sorbate, 0.6 to 1.5 parts of antioxygen, 3 to 7 parts of dispersing agent, 1.5 to 4.5 parts of defoaming agent, 20 to 50 parts of pigment, and 10 to 30 parts of water are adopted, so that the problems that a silk-screen embossed oil process is adopted for printing when a small box product is printed, but the embossed oil printing production efficiency is low, and the printing ink is wasted severely are solved; and the single-concave embossed oil printing process has the advantages of high production efficiency and less printing ink waste.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a single concave-convex ink printing process. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate-making, ink application, and pressurization to reproduce the contents of the original manuscript in batches. In the literal sense, writing with traces is called printing, and rubbing is called brushing. Use a brush to rub and make traces on other objects, which is called printing. In short, printing is the industry that produces printed matter. The production of printed materials is similar to that of seals. First engrave the seal (plate), then dip the seal (plate) with ink, and then transfer the ink on the seal (plate) to paper, silk, leather and other substrates to form a printed matter. Computer printed documents can be printed by laser printers, inkjet printers or ot...
