Problems solved by technology

At the same time, in order to further pursue refinement, most manufacturers use stainless steel wire mesh for production. However, stainless steel mesh hinders the penetration of ultraviolet rays. In the case of ensuring the accuracy of the screen image and text, even if the peak value of the optimal exposure is used, the screen will still appear. The film on the squeegee surface of t

Embodiment Construction

[0022] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby clearly defining the protection scope of the present invention.

[0023] See figure 1 , the present invention provides a method for improving the printing durability and transmittance of the screen plate of the light guide plate, and completes the entire plate-making and photo-printing work by secondary coating and exposure, including the following steps:

[0024] 1. For the design and production of the film draft, first use AutoCAD software to design the original graphics, and make symmetrical marks on the four corners of the graphics area, such as figure 2 As shown, the alignment mark used for the second exposure is called the first draft film; secondly, keep the center line of th...

Abstract

The invention provides a method for raising light guide plate screen press run and permeability. The method comprises the following steps that a, the design and production of a film negative comprises the following steps of designing the needed negative pattern firstly, symmetrically marking on the four corners of the periphery of the pattern for the counter point of a second exposure and creating a second draft pattern, remaining the same center line of the negative secondly, broadening 50 Mu m of each object line width of the pattern, creating a second draft pattern and producing two sets of films; b, coating and printing comprises the following steps of coating and exposing twice, using different natures of two photosensitive emulsions in the twice coating. Due to the fact that different natures of the two photosensitive emulsions are used in the coating, the print resistance and the permeability of the screen is improved greatly, production cost is reduced greatly.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a manufacturing process of a precision light guide plate screen. Background technique [0002] The LED panel lights that are popular in the market today are favored by consumers. The LED panel light has a unique design. The light passes through the light guide plate with high light transmittance to form a uniform plane luminous effect. The uniformity of illumination is good, the light is soft, comfortable and bright, which can effectively relieve eye fatigue. The design principle of the light guide plate is derived from the LCD screen of the notebook computer, which can transform the line light source or point light source into a uniformly luminous surface light source. The light guide plate is made of optical-grade acrylic / PC sheet, and then high-tech materials with high reflectivity and non-absorbing light are used to print light-guiding points on the bottom of the optical-gr...
