We produce flexible printing plates specially designed for alignment film printing on liquid crystal panels. Tiny concave-convex patterns (halftone dots) are formed on the plate surface to maintain uniform ink distribution, enabling high-quality thin-film printing.
It is mainly adopted for printing alignment films (PI films) of STN, C-STN and TFT-grade LCD products. It can print PI films that are thinner, more uniform and with higher dimensional precision, making it a dedicated matched tool for alignment film printing in the LCD industry at present.
