What are the specific steps of screen printing and drying (sizing)?

There is nothing wrong with your method, but because of the shearing motion of the scraper, the screen on the side in contact with the scraper is seriously worn. It is best to glue the side in contact with the scraper for two or three times, and scrape the back in contact with the substrate only once to collect the glue. This treatment will reduce the thickness of the screen, which is beneficial to dry thin lines or halftone patterns.

When a pattern with a particularly large paddle is needed, the size can be adjusted back and forth many times to increase the thickness of the screen.

The principle of screen sizing is: flexible adjustment, and appropriate adjustment of sizing times according to different pattern/fineness requirements/order quantity.
