Technical Field

Background
The computer-to-plate technology (computer to plate, abbreviated as CTP) is a technology in which a document text image is digitally processed and typeset and edited by a computer, directly scanned and imaged on a printing plate, and then subjected to post-processing procedures such as development, fixation and the like or post-processing-free to prepare the printing plate. Currently, CTP direct platemaking machines are generally classified into three major categories of an inner drum type, an outer drum type, and a platform type, among which the most used are the inner drum type and the outer drum type, and the outer drum type gradually shows a mainstream trend.
External drum imaging is where the plate is wrapped around the surface of a cylinder and when the cylinder rotates in the circumferential direction at a speed of a few hundred copies per minute, the plate rotates at the same speed as the cylinder. Simultaneously with this, laser light is irradiated on the printing plate, thereby completing scanning of the printing plate. The outer drum type CTP has the advantages of being suitable for large-format printing plates, being mostly suitable for heat-sensitive printing plates, being capable of simulating the curvature of the printing plate of the printing machine and ensuring the printing precision as the printing plate is arranged outside the cylinder and is in the same state as the printing plate on the printing machine. However, the cylinder cannot rotate at a high speed during the plate making process, and a specific counterweight balancing device is required to maintain the balance stability of the printing plate when the cylinder rotates to ensure the rotation stability.
The dynamic balance of the drum CTP is commonly in the market at present in a magnetic attraction type structure which is locked by self friction after adjustment or in a structure which is locked by a gear after adjustment. After a period of operation, the offset of the dynamic balance weight can not be found, so that the probability of the equipment to produce defective products is increased.
