Due to the large amount of data, we usually need software programming to achieve this, she said, and the production of the master plate is often similar to that of the semiconductor lithography process, in which the laser is just an energy release device, with which a metal impression template is formed through electrochemical deposition. The resulting master plate is then coated on a steel molding roller while the film surface is formed with the same micro nano structure as the master plate by heating and pressurizing
