What is the reason for the shrinkage of screen printing patterns?

The scale of the printed pattern is incorrect.

The maximum printed pattern should be 70% of the inner diameter of the screen, otherwise it is difficult to overprint and the four-sided image will be deformed.

Printed matter is exposure, and printed matter is the work of photocopying images and texts on high transparency carriers such as film and sulfuric acid paper to materials coated with photosensitive materials such as screen, PS and resin through exposure.
