Embodiment 1

[0035] The paper printing process with three-dimensional laser effect pattern of the present embodiment comprises the following steps:

[0036] 1) Offset printing is carried out on one surface of paper (white card);

[0037] 2) Obtain a laser effect on the offset printing ink layer on the surface of the paper;

[0038] 3) Screen varnish printing is carried out on the surface of the paper which has undergone the offset printing in step 1 and the treatment in step 2 in sequence.

[0039] The above step 2 includes the following sub-steps in turn:

[0040] 2.1) Select 90% dots of film and screen printing cold stamping plate;

[0041] 2.2) transfer the UV curing transfer adhesive to the printed offset printing ink layer by the above-mentioned screen printing cold stamping plate, and form a UV curing transfer adhesive layer with a uniform thickness on the offset printing ink layer;

[0042] 2.3) Composite laser transfer film on the UV curing transfer adhesive layer;

[0043] 2.4...

Embodiment 2

[0052] The difference between the paper printing process with three-dimensional laser effect pattern and embodiment 1 of this embodiment is:

[0053] In the step 2, the mesh of the screen printing film is 500 mesh, and the UV curing transfer glue is applied 3 times; the printing speed is 2500 sheets / hour.

[0054]In the step 3, the mesh is 300 mesh, and the UV curing screen printing embossed varnish is applied 3 times and 3 times; printing speed: 2500 sheets / hour.

Embodiment 3

[0056] The difference between the paper printing process with three-dimensional laser effect pattern in this embodiment and the paper printing process with three-dimensional laser effect pattern in embodiment 1 is:

[0057] In the step 2, the mesh of the screen printing film is 450 mesh, and the UV curing transfer glue is applied twice; the printing speed is 2200 sheets / hour.

[0058] In the step 3, the mesh is 280 mesh; printing speed: 2200 sheets / hour.

Abstract

The invention relates to a printing process of paper having a pattern with the three-dimensional laser effect, which is characterized by comprising the following steps: carrying out offset printing on one surface of the paper; leading an offset printing ink layer on the surface of the paper to obtain the laser effect; and carrying out screen varnish printing on the surface of the paper, wherein the offset printing in the step 1 and the treatment in the step 2 are sequentially carried out on the surface. The printing process has the benefits of reducing the cost by 20%-40%, being more environment-friendly, ensuring the product quality, leading the whole product to have beautiful appearance and strong three-dimensional sense, leading the printing effect to be more abundant and realizing stronger texture effect.

Description

technical field [0001] The invention relates to a printing process, more specifically to a paper printing process with three-dimensional laser effect patterns. Background technique [0002] In general, lamination of laser film or large-area bronzing on white cardboard can obtain laser effects, but this will greatly increase production difficulty and processing costs, and the processed products contain high benzene, so they do not meet the requirements of environmental protection . [0003] Such as production transfer (laser effect) gold cardboard, the main process of processing is as follows: [0004] 1. Make PET transfer silver film; [0005] 2. Pre-coat the transfer glue on the PET transfer silver film; [0006] 3. The side of the PET transfer silver film coated with the transfer glue is wet-laminated with the paper substrate; [0007] 4. Parking and solidification; [0008] 5. Peel off the PET base film of the PET silver transfer film; [0009] 6. Apply color paint ...
