Problems solved by technology
[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and to provide a manufacturing process of the screen plate, aiming at solving the problem that the size of the screen plate is deformed due to the expansion of the vacuum pressure during the process of printing and vacuuming the screen plate. The technical problem of inconsistency between the size of the plate and the standard size

Embodiment Construction
[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] Such as figure 1 As shown, in the printing method of the screen plate provided by the embodiment of the present invention, the screen plate includes a screen frame and a screen frame surface stretched on the screen frame, and a pattern area is provided in the middle of the screen frame surface. The bottom of the pattern area is provided with a film corresponding to the pattern area, and the area defined by the periphery of the pattern area and the inner frame edge of the screen frame is the non-pattern area of the screen frame surface, including the following s...

Abstract
The invention discloses a printing-down method for a screen printing plate. According to the method, a transparent PET gasket is arranged in a non-pattern region of a screen frame surface and takes supporting and light-transmitting effects, so that the phenomenon of tension deformation of a screen printing plate surface generated under the action of vacuum pressure is avoided, and the screen printing size during a printing-down process can be accurately copied; and meanwhile, an air guide rope is arranged around the screen printing plate, so that close contact between a rubber blanket and a screen frame of the screen printing plate during the printing-down process is delayed, vacuum suction duration is prolonged, air between the concave-surface rubber blanket in the screen frame and the screen printing plate can be exhausted as far as possible, the rubber blanket is closely combined with a screen gauze surface more fully, and the stability of pattern lines and overall size of the screen printing plate is ensured.
Description
technical field [0001] The invention relates to the technical field of screen printing, in particular to a screen drying method. Background technique [0002] At present, it is widely used in the field of touch screen. In order to improve production efficiency and reduce production costs, the screen size of most screen printing screens is printed with a screen size of 800*800mm or above, because multiple images need to be displayed on one screen. Element size (1~100) pcs, in order to ensure the accuracy of each graphic element size on the screen, the overall shape accuracy of the screen during the production process needs to be controlled within + / -0.05mm, but, in fact, in the screen Due to factors such as changes in temperature and humidity and vacuum pressure during the printing process, the size of the film and the screen size during the printing process will change, resulting in deviations between the screen size and the standard size, resulting in deviations between the...
