Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] The film is static laser printing, the accuracy is controlled at 0.01%, the length*width is required to be 2799MM*2995MM, the coverage rate is 40% dot glazed glass, and the laser film splicing method realizes one-time printing. The specific method is:

[0020] 1. Take two 3000mm*1500mm laser film sheets with the same dot pattern 3. The seams are overlapped by the upper and lower films, and the dots of the upper and lower film sheets should be completely overlapped.

[0021] 2. Then use a special punching tool to remove the glaze spots on the overlapping parts of the film. The upper film sheet 1 is convex cut, and the next film sheet 2 is concave cut (such as figure 1 ).

[0022] 3. After cutting, spread the two sheets of film on the pre-drying screen, and make the concave and convex sides approach horizontally (such as figure 2 ), an...

Abstract

The invention relates to an ultra-wide silk screen dot print film splicing method. The method includes the following steps that two or more laser film pieces with same dot patterns are manufactured, the film pieces are overlapped and spliced, so that the overlapped width is just the needed width of a silk screen, and the dot patterns on the upper and lower film pieces at spliced joints are completely coincident; dots of overlapped parts of the film pieces are removed through a hole punching tool, therefore the dot patterns are arranged at intervals, and the edges of the sides of the upper and lower film pieces form concave-convex structures which can be mutually embedded and matched in a concave-convex mode; and after cutting, the two film pieces are flatly spread on a pre-sunned screen printing plate, horizontal embedding-matching approaching of the concave and convex edges is performed, the spliced positions are fixed through transparent adhesive tape, then air pumping, flattening and exposure are started, and ultra-wide film is obtained. According to the ultra-wide silk screen dot print film splicing method, a semi-circle concave-convex embedding-matching mode is adopted, so that the two film pieces are spliced to form a large film piece, the spliced joints are small, and one-time printing is only needed; and the printed patterns do not have spliced lines which exist during two-time printing and splicing, and the dot patterns in the spliced positions are complete and attractive.

Description

technical field [0001] The invention relates to the technical field of glass screen printing, in particular to a film splicing method for ultra-wide screen dot printing. Background technique [0002] Screen printing consists of five major elements, namely screen printing plate, squeegee, ink, printing table and substrate. The basic principle of screen printing is: use the basic principle of the screen printing plate's graphic part of the mesh to penetrate ink, and the non-graphic part of the mesh to be impermeable to ink. When printing, pour ink into one end of the screen printing plate, apply a certain amount of pressure on the ink part of the screen printing plate with the scraper, and at the same time, print towards the other end of the screen printing plate. The ink is squeezed by the scraper from the mesh of the graphic part to the substrate during the movement. Due to the viscosity of the ink, the imprint is fixed within a certain range. During the printing process, ...
