Simulation printing method of nonlinear thin film material

Abstract

The invention discloses a simulation printing method of a nonlinear thin film material. The method comprises the following steps: (1) transfer printing activation: adding an activating agent to enablea transfer printing PVA thin film to enter an activated state; (2) simulation calculation: performing modeling and simulation according to a transfer printing model of a three-dimensional object, andsimulating stretching and deformation processes; (3) acquiring of a pre-deformation pattern: acquiring the transfer printing pre-deformation image according to an analogue simulation result; (4) layer planning: dividing the image into a PVA film carrier layer, a protective layer and a pattern layer according to the requirement of the thin film material; and (5) image-text transfer printing and rolling storage: printing the pre-deformation image and other image layers on the PVA thin film through intaglio printing. Intaglio printing equipment comprises a base, a protective layer printing mechanism, a boundary layer printing mechanism, an image printing mechanism and a winding mechanism. Multi-layer printing is set, one-time coating forming of the image and the protective layer is realized,independent brushing of the protective layer is avoided, boundary layer printing is set, and deformation of the image in the transfer printing process is greatly reduced.

Description

Technical field[0001]The invention belongs to the field of film printing, and in particular relates to a simulation printing method of nonlinear film materials.Background technique[0002]Gravure printing has always been the main printing method for high-end printing and film printing due to its excellent printing quality and friendliness to substrates. The existing water transfer film printing methods on the market generally directly print the ink on the gravure printing machine. On the water-soluble PVA film, the ink layer is in direct contact with the water-soluble film. When the PVA film is saturated with water, the ink layer swells and spreads, deforms and shifts, resulting in color difference, which seriously affects the coating quality of the product surface; The surface of the film coated by this printing method is high in hardness, tough and fragile, and has poor resistance to rubbing. Therefore, after the transfer is completed, a protective layer is coated on the surface of ...

[0002] Gravure printing has always been the main printing method for high-end printing and film printing due to its excellent printing quality and friendliness to substrates. The existing water transfer printing film printing methods on the market generally directly print ink on the surface through a gravure printing machine. On the water-soluble PVA film, the ink layer is in direct contact with the water-soluble film. When the PVA film is saturated with water, the ink layer absorbs water and swells, and diffusion, deformation and displacement occur, resulting in chromatic aberration, which seriously affects the coating quality of the product surface; moreover, this The surface of the film covered by this printing method has high hardness, is tough and brittle, and has poor rubbing resistance. Therefore, it is very cumbersome to apply a protective layer on the surface of the film after the transfer is completed.
