In some embodiments, a screen printing plate 10 includes a metal mesh part 13 and a metal mask part 14 provided on one side of the metal mesh part 13 integrally with the metal mesh part 13. In addition, the metal mask part 14 has an opening part 14a, and when the dimension from the outer edge 14a2 of the opening part 14a to the metal mesh part 13 represents a fill depth, this fill depth is the largest in the part corresponding to the center area of the opening part 14a. The screen printing plate does not cause the actual printing thickness to vary easily, even when the target printing thickness is reduced.

A manufacturing method of flexible substrates via a screen printing machine includes moving the back-ink blade and the scraper, the scraper is above the back-ink blade, and the back-ink blade is configured to coat the adhesive material on the opening; moving the back-ink blade and the scraper along an opposite direction, the scraper is lowered down to a position below the back-ink blade, the scraper prints the adhesive material from the opening to the substrate so as to form a flexible substrate thin-film corresponding to the opening area on the substrate; and applying a baking process on the flexible substrate thin-film to obtain a cured flexible substrate. The screen printing machine forms the flexible substrate thin-film corresponding to the opening of the screen printing machine to so as to obtain the flexible substrate having a predetermined dimension, which simplifies the manufacturing process and saves the manufacturing cost.

A system includes a frame, an ultraviolet light source, an LCD panel, and a computer. The frame is configured to retain a substrate to be converted into a silk screen stencil. The LCD panel is positioned between the frame and the ultraviolet light source. The computer is coupled to the LCD panel. The computer is configured to transfer image data to the LCD panel. The image data defines an image to be transferred to the substrate.
