Letterpress printing machine is an important printing equipment, so what are the common types of letterpress printing machine?
There are three main types of letterpress printing machines: flattening, rounding and rounding. Flatbed letterpress presses are also known as flatbed presses. The plate table and the imprinting mechanism of the printing plate are flat. When working, the printing plate is in perfect contact with the imprinting plate. The total pressure that the machine bears at one time is relatively large, and the relative imprinting time is relatively long. This kind of printing machine requires the printing plate and the imprinting plate to be flat, and the printing format is not large; the circular flattening letterpress printing machine is also called a flatbed printing machine. . When the machine is working, the plate table moves back and forth, and the printing speed is limited, so the output is not high; the circular pressure circular letterpress printing machine is also called a rotary printing machine. When the machine is working, the impression cylinder moves with the printed matter and is in contact with the plate cylinder. The impression cylinder and plate cylinder rotate continuously and rapidly, so the productivity is high.
