First, CTP direct plate-making machine can usually be classified according to the exposure mode and the source of the plate-making machine 1, according to the exposure classification According to the classification of exposure methods, it can be divided into inner drum type, outer drum type and flat type type. The most used types are inner drum type and outer type drum type. The inner drum type is mainly used for large format plates such as newspapers, such as Agile's Galileo VS system, ECRM's Wildcat/Tigercat system, and the outer drum type is suitable for thermal plates such as Kerry. Orsay Angel's Lotem series products; platform type is especially suitable for aluminum base, such as Barco's Mondrian system. 2, according to the exposure classification In recent years, a new type of violet laser light source has been gradually adopted for many new CTP systems, and it is in parallel with red laser light sources and green laser light sources. Using the violet laser as the CTP plate making light source, the energy consumption of the equipment is lower than before, and the manufacturing cost of the equipment can be greatly reduced, and the applied plate material is also cheaper. Agfa's latest GalileoViolet and MitsuhishiChemical's lv-1/cobat8CTP platemaking system are all such products. Second, CTP plate can usually be classified according to the base and coating 1, according to the base classification At present, the types of plates can be divided into metal plates and polyester plates according to the plate base. Metal plates mainly refer to aluminum plate materials, which have high resistance to printing and are suitable for long-printing. The polyester plate is more able to meet the requirements of short-run printing. 2, according to the coating classification Plates can be divided into photosensitive resin plates and thermal plates according to the coating. Photosensitive resin plates are suitable for medium-to-long-color commercial printing. The main products are Agfa's N91 photosensitive resin plate and Mitsubishi's LA-S type. Thermal plate can be processed under yellow light or filtered sunlight, and its plate making quality is currently the best. The main products are Kodak PolyLight's 830nm thermal plate and Fuji's LH-N1 thermal plate.

â‘ conveying capacity: Conveyor capacity refers to the amount of material transported per unit of time. In the delivery of bulk material, the hourly delivery of material mass or volume calculation; in the delivery of articles into pieces, the number of hours per hour delivery.
â‘¡ conveying speed: improve the transmission speed can improve the transmission capacity. When the conveyor belt is used as a pulling member and the conveying length is large, the conveying speed is increased. However, high-speed operation of the belt conveyor should pay attention to vibration, noise and start, braking and other issues. For the chain as a tractor conveyor, conveyor speed should not be too large to prevent increased power load. At the same time the process of operation of the conveyor, conveyor speed should be determined in accordance with the production process requirements.
â‘¢ component size: conveyor component size, including conveyor belt width, strip width, hopper volume, pipe diameter and container size. The size of these components directly affect the transport capacity of the conveyor.
â‘£ conveying length and inclination: the length of the transmission line and the size of the angle of a direct impact on the total resistance of the conveyor and the required power.
