Ultra-wide silk screen dot print film splicing method

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, ...

AI Technical Summary

Problems solved by technology

The splicing of ultra-wide screen dot patterns has always been a major problem in screen printing. The conventional two-splicing printing efficiency is wasted by 1 times, and the quality is difficult to control. It seriously affects the appearance, which is unacceptable to many customers. The global screen printing width is hovering at the limit of 2.5 meters. The designer's thinking is restricted, and the different architectural styles are contained.
