Embodiment Construction

[0013] Example 1 First, print patterns on the reverse side of plastic sheets and other substrates, dry or cure them, print reverse ink on the surface of plastic sheets according to the specified position, and then partially apply curable resin varnish off-line to partially apply curable resin varnish At the same time, it must cover the area coated with the reverse ink, so that the two repel each other to produce a grating stripe structure, and finally make the product.

[0014] Example 2 First, print patterns on the reverse side of plastic sheets and other substrates, dry or cure them, print reverse curing resin inks on the surface of plastic sheets, and then apply cured resin varnish partially or fully offline or on-line to perform local Or when fully coating the curable resin ink, it must cover the area coated with the reverse ink, so that the two repel each other to produce a grating stripe structure, and finally make the product.

Abstract

A pattern layer is printed on back face of transparent plastic plate. Grating streaked image is printed on partial position on surface layer of the plastic plate through converse printing ink. Solidifying type smooth resin is coated on specified position needed roundly. Mutual exclusion between solidifying type smooth resin and converse printing ink forms arches so as to build structure of grating image. Technical steps are as following: printing pattern on back face of object to be printed, and drying or solidifying the pattern; printing partial converse ink on the surface of the said object in off line or in series; coating solidifying type smooth resin partially or roundly in off line or in series so as to produce products. Comparing with prior art, the offset printing method possesses advantages: fine grating structure, quick procedure, accurate positioning, and raised production efficiency. The invention renovates packing technique.

Description

[technical field] [0001] The invention relates to the technical field of printing and packaging, in particular to a lenticular photo produced by printing and coating and a production process. [Background technique] [0002] As we all know, in the packaging printing process, it is common to make the surface of the substrate into a grating effect. Generally speaking, the grating can be made by extrusion or hot pressing, and the grating can also be made of a screen. This method often generates static electricity, and the surface is easy to be stained with dust, which will easily lead to a decline in quality, and the output is not large. Another method is to use flexographic printing to make gratings. The grating stripes produced by this method are not fine enough and difficult. Also big, photo effect is not good. [0003] Chinese patent 200410053525.8 introduces a process of reverse partial glazing. This patent introduces a special ink, that is, reverse ink. The surface energ...
