CTP platesetters are generally divided into four categories: inner drum type, outer drum type, flat type, and curved type. Among the four types, the most used ones are the inner drum and the outer drum type; among them, the high-end CTP platesetter with good performance is the outer drum type. This article will introduce you to the plate making machine limitation. In general, the reflectivity provided by the plate supplier can only be used as a reference. We need to use the Focus Cal reflect to automatically measure the left, middle and right positions of the plate. The average value obtained is the reflectivity of the plate. This value is not standard, and the reflectivity of different plates is not the same, so it is very important to adjust the reflectivity when changing the plate to a new plate. The surface reflectance is used for the machine to detect the edge. Different plates usually have different surface reflectance. If the reflectance is not set correctly, the machine may report an error without finding the edge, so that normal plate making cannot be performed. CTP technology is the continuation and development of the laser photo-alignment process and the PS plate process. The biggest difference between the sensitization mechanism of the sensitization and the PS plate is that the PS plate exposure uses an ultraviolet spot source. In the printing plate, in addition to direct illumination, there are scattered and refracted light, and the loss of light energy is relatively large. However, the laser light source of the laser plate making system is mostly monochromatic light, generally selecting one wavelength or a range of wavelengths, which is the laser. The advanced position of the plate making machine. At present, the newspaper printing industry uses the most traditional plate-making technology and CTP direct plate-making technology. Traditional plate-making technology produces hazardous substances, which are harmful to the environment, while the process is backward and the efficiency is low. High-speed CTP direct plate-making technology Foreign monopoly technology, high equipment prices, high cost of consumables, and there are still pollution problems caused by exposure and development. The nano-material green plate-making equipment is low in price and has no environmental hazard, which will lead the industry change and is likely to become the future development trend of the newspaper printing industry.
