Background

A printer is a machine that prints text and images. Modern printing presses generally consist of mechanisms for plate-setting, inking, stamping, paper transport, etc. The printing machines are classified by form into a letterpress printing machine, a lithographic printing machine, an intaglio printing machine, and a screen printing machine, of which the letterpress printing machine is the first choice for printing cards.

The detailed process of letterpress printing is as follows: the ink feeder distributes the ink evenly and then transfers the ink to the printing plate by the inking roller. The paper feeding mechanism conveys paper to the printing part, and under the action of printing pressure, the ink of the image-text part of the printing plate is transferred to a printing stock, so that the printing of a printed product is completed. The printed printing stocks are temporarily piled on a paper bearing table and are uniformly transferred after a certain quantity.
