Is the photosensitive material used for printing the same as that used for photography?

The principle is the same, but not the same.

There are two kinds of photosensitive materials on printing:

1. photosensitive film for induction laser, used for plate making.

2. The photosensitive printing plate can feel ultraviolet rays. The principle is that the prepared photosensitive film (laser phototypesetting) has transparent parts and opaque graphic parts (only black, no gray, and the gray inside the printed matter is also composed of countless tiny pure black spots). Put the photosensitive film on the photosensitive printing plate and print it under the ultraviolet lamp. The opaque part on the photosensitive film blocks the ultraviolet light, so that the printing plate part is not affected by the ultraviolet light.

In theory, photographic film can be enlarged to replace photographic film, but now photographic film technology is gradually being abolished. Due to the price and environmental protection factors, ctp direct plate-making technology saves the steps of photographic film plate-making
