The moisture content of paper is a variable, and it is the first factor that determines the deformation of paper. When the fiber absorbs moisture, expansion occurs, which increases the linear size of the paper and increases the area. As a result, the size of the image printed on the paper increases and the area increases.
The back of the paper is stretched due to the influence of humidity, causing troubles for the overprinting of the next color, without any change in the front gauge and the side gauge. We used a 80g/m2 bond paper to fold a tie-style paper model, glued in the middle of the paperboard, so that after the first paper into the embossing, the top of the paper was raised 2~3mm for embossing, and the effect was less convex than the rear tip. The paper can be overprinted properly.
In the case of paper stretching too severe, a half-overprint method can achieve better printing results.
According to the conventional method, when the half-overprint is performed, the left half of the image on the printing plate is first removed, the right half of the graphic is overlaid, and then the right half of the graphic on the plate is eliminated, and the left half of the graphic is overprinted. Although this can solve the problem of misregistration due to paper stretching, it is too wasteful. According to the size of the pattern, we cut half of the lining and paper of the rubber bridge and printed the image of the left half under the same pressure, and then overprinted the right half of the image. The result was very good.
