[0002] Printing cylinders are an indispensable and key component in modern printing technology. They are mainly used to transmit graphic information and transfer the ink from the printing plate to paper or other printing materials through rotation. The cylinders are usually made of metal or composite materials, and the surface is precisely processed to ensure flatness and durability. They may contain heating or cooling devices inside to accommodate different types of ink and paper. According to their functions, printing cylinders can be divided into three types: plate cylinders, rubber cylinders, and impression cylinders. The plate cylinder is responsible for carrying the printing plate and transferring the pattern to the rubber cylinder. The rubber cylinder contacts the paper through elastic deformation to achieve ink transfer. The impression cylinder is used to provide the necessary pressure to ensure the clarity of the image and text. In addition, with the development of digital printing technology, some new cylinders have integrated electronic components, which can achieve more precise positioning and control, improving printing quality and efficiency.
