Embodiment 1

[0032] A method for screen printing double-layer stretching, comprising the steps of:

[0033] S1: welding and pressing the 50-mesh square mesh steel mesh on the mesh frame;

[0034] S2: Stretch the 50-mesh circular mesh gauze on the screen frame welded with steel mesh;

[0035] S3: Use the CCD camera to capture the shape of the mesh after the double-layer stretched mesh;

[0036] S4: Adjust the angle and position of the gauze and the steel net according to the captured image, so that the overlapping angle is 0°, and the position is shifted by a half-purpose distance along the horizontal direction, so that the shape of the mesh meets the predetermined requirements.

Embodiment 2

[0038] A method for screen printing double-layer stretching, comprising the steps of:

[0039] S1: Weld and press the 50-mesh diamond mesh steel mesh on the mesh frame;

[0040] S2: Stretch the 100-mesh circular mesh gauze on the screen frame welded with steel mesh;

[0041] S3: Use the CCD camera to capture the shape of the mesh after the double-layer stretched mesh;

[0042] S4: Adjust the angle and position of gauze and steel mesh according to the captured image, so that the overlapping angle is 45°, and the positions are offset by half the purpose distance along the horizontal direction and the vertical direction, so that the shape of the mesh meets the predetermined requirements.

Embodiment 3

[0044] A method for screen printing double-layer stretching, comprising the steps of:

[0045] S1: welding and pressing the 100-mesh square mesh steel mesh on the mesh frame;

[0046] S2: Stretch the 100-mesh circular mesh gauze on the screen frame welded with steel mesh;

[0047] S3: Use the CCD camera to capture the shape of the mesh after the double-layer stretched mesh;

[0048] S4: Adjust the angle and position of gauze and steel mesh according to the captured image, so that the overlapping angle is 0°, and the position does not shift along the horizontal direction and the vertical direction or is shifted by an integer distance, so that the shape of the mesh meets the predetermined requirements.

Abstract

The invention provides a double-layer screen stretching method for silk-screen printing, and relates to the technical field of package printing. The double-layer screen stretching method comprises the following steps that S1, a steel stencil is welded and pressed on a stencil frame; S2, a gauze element is stretched on the stencil frame welded with the steel stencil; S3, a CCD camera is used to shoot the shape of meshes after double-layer screen stretching; and S4, the overlapping angle and position of the gauze element and the steel stencil are adjusted according to shot images, so that the mesh shape meets a preset requirement. Through matching of different shapes, mesh numbers and overlapping angles in the two layers of stretching nets, the shapes and sizes of the meshes can be adjusted at will, and the printing effect different from that of traditional silk-screen printing is achieved. And the special mesh-shaped printed image-text has a certain anti-counterfeiting effect. By arranging the steel stencil and the gauze element which are different in thickness, the depth of the meshes can be changed, so that printed images and texts are concave and convex, a certain embossment effect is achieved, and more exquisite images and texts are presented.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular to a double-layer stretching method for screen printing. Background technique [0002] In the screen printing process, the ink leaks to the surface of the substrate through the meshes of the graphic on the screen, and the ink dots leaked from each mesh form an image. However, with the demand for personalization, delicacy and anti-counterfeiting effects of product packaging, the requirements for screen printing effects are becoming more and more changeable. The graphic effect composed of different dot shapes is an important aspect of the screen printing effect. [0003] At present, the most widely used dot shapes are round dots, square dots, diamond dots and oval dots. Traditional screen printing usually uses different dot shapes to make plates separately. Every time the dot shape is changed, the plate needs to be re-made. The screen with special shape mesh is often expen...
