Screen printing process

Abstract

The invention discloses a screen printing process, which comprises the following steps of slitting and blanking a curtain, and slitting the curtain into a size required by typesetting; under the conditions of constant temperature and constant humidity, carrying out all-around white ink brushing on the curtain in a reverse roller coating manner, and drying after brushing; then coating the UV blackink through a printing plate in an offset printing manner under the constant-temperature and constant-humidity conditions, and drying after coating. By combining the reverse coating and offset printing modes, the operation method is simple, the cost is low, and the screen printing process is easy to popularize and use in a large range.

Description

technical field [0001] The invention relates to the technical field of electronic product printing, and more specifically relates to a screen printing process. Background technique [0002] At present, the application of projectors in meeting rooms and teaching environments has become more and more common. When people present complex tasks, or when explaining based on the structure of complex things, they will use projectors to show and describe related solutions to the audience. This kind of The way of use can be perfectly displayed in places with dim lighting, but the effect in high-brightness environments is not very ideal. Due to the diffuse reflection caused by ambient light, the projector will suffer from severe whitening phenomenon under strong light, and it may even be unusable.

Problems solved by technology

[0002] At present, the application of projectors in meeting rooms and teaching environments has become more and more common. When people present complex tasks, or when explaining based on the structure of complex things, they will use projectors to show and describe related solutions to the audience. This kind of The way of use can be perfectly displayed in places with dim lighting, but the effect in high-light environments is not very ideal

Due to the diffuse reflection brought by the ambient light, the projector will suffer from severe whitening phenomenon under strong light, and it may even be unusable

[0003] Since the research on the projector itself is already at a serious bottleneck stage, in this case, improving the projection screen used in conjunction with the projector is an important direction to solve the above-mentioned whitening phenomenon, and there are some good technologies on the market path, but the technical path to realize the product is very complicated, the cost is high, and it cannot be promoted and used on a large scale
