Question

Diff between electronic cylinder and chemical cylinder

Answer 1

Answer:

Explanation:

Cylinder Printing. ... The engraved printing cylinder was placed horizontally with another cylinder above it. The bottom of the lower cylinder took up the printing colour from a trough, the excess being scraped off by a closely fitting steel blade.

Gravure is small cells recessed into a cylinder that hold ink. The cylinder is washed with ink; a doctor blade removes the excess, leaving ink only in the cells. The ink is transferred to a substrate (paper, plastic, film, and more) using a rotary press. Rotogravure, or gravure, is an old process.
