Industrial printing process of double-layer label

Abstract

The invention relates to an industrial printing process of a double-layer label. The industrial printing process comprises the following steps: unwinding a second-layer printing material through an unwinding mechanism of a printing machine, then printing a pattern or characters on the surface of the second-layer printing material according to a design requirement, drying the surface after printing is completed, printing a layer of removable gloss oil on the surface to protect the pattern or the characters, and drying for later use; combining a glue layer of an unwound first-layer printing material with a surface layer of the second-layer printing material to obtain a double-layer label material, and drying the material; and according to the design requirements, printing a pattern or characters on the first-layer printing material and the removable gloss oil, and performing die cutting to obtain the double-layer printed label. The double-layer label is printed by adopting a definite process, so that the glue layer is not needed to be aligned accurately, drawing of a material is avoided, consumables are reduced, and the possibility of waste of the material is decreased; and meanwhile, the printing time is shortened, and the obtained double-layer label is stable in quality and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to an industrialized printing process for double-layer labels with simple process, low equipment requirements and stable quality. Background technique [0002] Double-layer labels are increasingly widely used in daily chemicals, food, pharmaceuticals, electronic products and household daily necessities. They can cover a huge amount of information in a small size, including internal label printing, multilingual product ingredients or instructions for use. , which helps to prevent counterfeiting and is also an ideal tool for promotion. At present, the printing of double-layer labels requires two printing machines. When unwinding, compounding, and printing at the same time, the two layers of label materials need to be completely aligned, which requires high technical requirements for equipment and operators, and its stability is not good. It is easy to stretch and deform,...
