Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] The multi-color gravure printing method is used to print water-based ink on aluminum-sprayed paper. The method is realized by a multi-color on-line gravure printing machine. The multi-color on-line gravure printing machine is composed of multiple printing color groups, and each printing color group One color of ink can be printed, and the graphic printing is completed after the paper passes through each printing color group in turn. So that the water-based ink just printed on the surface of the paper is dried and solidified on the surface of the paper before reaching the next printing color group. Generally, the drying system blows hot air to the paper to make the ink on the paper dry and solidify quickly. However, after the paper is heated, it is easy to expand along the direction perpendicular to the paper fiber, so it is easy to have overprint deviation dur...

Abstract

The invention discloses a multicolour photogravure method which uses spray Al paper as printing paper and waterborne ink as printing ink. During the printing process, firstly a layer of polyacrylate emulsion coating is printed on the spray Al paper, and after the polyacrylate emulsion coating is dried and cured, the waterborne ink is used for printing. By adopting the scheme for printing, the polyacrylate emulsion coating has good adhesive force with the metal layer such as the surface of the spray Al paper and the waterborne ink also has high coating ability with the polyacrylate emulsion coating so that the ink and papers can be well combined by using the polyacrylate emulsion coating, thus achieving the aim of increasing the adhesive force of ink. The method of the invention realizes that the waterborne ink can be printed on the spray Al paper by adopting the photogravure method, and ensures that the spray Al paper and the waterborne ink which are two kinds of environmental protection type printing materials can be widely applied in the photogravure method field and the photogravure tends to develop in the green and environmental protection direction.

Description

technical field [0001] The invention relates to a printing method, in particular to a method for performing multi-color gravure printing with water-based ink on aluminum-sprayed paper. Background technique [0002] At present, the printing of cigarette packs is mostly carried out on a multi-color online gravure printing machine. When using a multi-color online gravure printing machine for printing, the liquid ink is printed on the surface of the paper through the printing plate cylinder. When the paper is printed from one printing color group to another printing color During the process of the printing group, the built-in drying device of the unit blows hot air to the paper, so that the ink just printed on the paper surface dries and solidifies on the paper surface before reaching the next printing color group. [0003] With the increase of people's awareness of environmental protection, people have higher requirements for the raw materials of printed matter, and the traditi...
