Hi, my friends! Today we will be discussing how to create high-quality screen plate for screen printing, also known as precision screens. In order to achieve excellent screen printing results, it is important to have a high-quality silk screen. So what are the standards for producing high-quality seen plates?
First, let us start by understanding what a screen plate is. A silk screen plate is made up of aluminum alloy frames, mesh screens, and photosensitive glue, as well as auxiliary materials such as screen adhesive, release powder, degreaser, screen polish, edge sealing glue, edge sealing silver paper, and sizing equipment.
To create a silk screen plate, you will need the following equipment: an electric or pneumatic mesh-stretching machine, a screen plate drying oven, a screen plate exposure machine, a high screen plate flushing table, a high-pressure flushing gun, and an air gun.
The process of creating a silk screen plate involves selecting a suitable aluminum alloy frame, choosing a suitable mesh screen based on the screen printing pattern and printing requirements, stretching the mesh screen and measuring its tension, cleaning and degreasing the mesh screen, applying photosensitive glue and low-temperature drying, attaching the silk screen film and exposing it using an exposure machine, wetting and developing with water for 2-3 minutes, flushing the non-photosensitive photosensitive glue off with a high-pressure flushing gun, and drying and inspecting the screen for defects.
To produce a high-quality screen plate, the aluminum alloy frame must be stable and not deformed. This is a prerequisite for ensuring the accuracy of the pattern alignment. The mesh screen selection is also important. For intricate patterns, a high mesh count yellow screen mesh should be selected, such as a 300 mesh or higher.
When stretching the mesh screen, repeat the process several times to ensure uniform tension and uniform thread diameter while maintaining stable high tension. Use screen polish to wipe the positive and negative sides of the screen several times to enhance the adhesion between the photosensitive glue and the mesh screen.
For products with high print volumes, the screen can be treated with a special material to improve the durability of the screen.
By following these steps, a high-quality, durable silk screen can be created.
In conclusion, creating a high-quality silk screen is essential for achieving excellent screen printing results. By using suitable materials and equipment and following a proper process, you can create a silk screen that will produce clear and accurate prints time after time. Thank you for reading and happy screen printing.
