Precision screen, also known as "screen", "mesh", or "stencil", is a crucial optical tool for photolithography, widely used in the making of relief, flat, and intaglio printing plates.

Precision screens are made of two pieces of optical glass or film etched with equal-width black and white parallel lines, which intersect at 90° to form a grid or a specific shape. The screen structures come in various forms, such as grid, circular, and chain patterns, with general specifications varying based on the specific application, typically ranging from 20-80 lines/cm to 60-100 lines/cm.

With the continuous advancement of technology and the rapid development of industry, the market demand for precision screens is on the rise. Currently, there are numerous manufacturers and suppliers of precision screens in the market, offering products with various specifications, materials, and applications. Consumers can choose the appropriate precision screen products based on their specific needs.
