What effect does the dry weather have on the printing workshop?

1. Paper expands when it absorbs water, but shrinks when it loses water.

2. Monochrome printing machine can't overprint when the paper is seriously deformed when it is dry, and multicolor printing will also have the phenomenon that one color is longer than another color in turn, or the dragging part is fan-shaped and "angular".

3. Overprinting is caused, or the front and back sides are inaccurate due to thermal expansion and contraction, or the printed paper is different in thermal expansion and contraction, which brings a lot of trouble to the next processing procedure. At this time, you need to buy a humidifier to eliminate the above problems.
