Abstract

The invention provides a production process of a nickel net for high-precision printing. The process comprises the steps of: 1, manufacture of a mould, 2, manufacture of a underlying net, and 3, manufacture of the nickel net. The production process is characterized in that: laser puncture adopted in mould manufacture is non-contact processing, cannot cause mechanical extrusion to a material, and protects the material from deformation; the processing precision can be 15mu m, the number of meshes can be 305, and the aperture ratio of a 305-mesh nickel net can be 14 percent; the work temperature of bath solution in manufacture of the underlying net is 45+ / -1 DEG C, the coating has good quality, and the treatment cost is low; application of additive No.1 and additive No.2 can improve the nickel deposition speed, so that nickel can be distributed on the anodic surface more uniformly, and the stability of the bath solution can be improved; when the nickel net is manufactured, tip casting off of the net in a process of producing the nickel net to the underlying net can be realized by a double-pulse power supply, occurrence of single horn shape in the prior art is changed, pore ends of the nickel net are manufactured into a shape of two approximately symmetric horns, and the aperture ratio of the nickel net and printing ink smoothness are improved.

Description

technical field [0001] The invention relates to a production technology of a nickel mesh, in particular to a production technology of a nickel mesh for high-precision printing. Background technique [0002] The application of screen printing in high-end tobacco, wine and food packaging cartons has increased significantly. However, due to the low printing speed, slow ink curing, difficult quality control and high printing costs of flat screen printing, it cannot meet the needs of large-scale mass production of cigarette cartons. .
