After the prepress design is completed, imposition is an important part of prepress technology. In order to save printing costs, different imposition methods need to be adopted for different printing machines. There are two imposition methods, one is rollover and the other is self-turning.
Rollover means that a printing plate is printed once on both sides of the paper. After printing once, the paper is turned over and rotated 180 degrees before printing the second side. When printing the second side, the direction of the paper's muzzle changes. After the printing is completed, cut in the middle to get two copies of the same printed product. The rollover method is shown in the figure.
Self-turning means that a printing plate is printed on both sides of the paper, but the turning method of the paper is the conventional turning method, and the nagging is unchanged. Its self-turning method is shown in the figure.
In short, no matter what kind of turning method, keep in mind, heaven and earth, earth to earth, not to be confused.
