The printing industry is an industry that has an important impact on China's national economy. Newspaper printing is the most common industry for printing technology. The biggest feature of newspaper printing and plate making is that the plate making speed is extremely high, the plate making volume is large and stable, and it is necessary to meet the newspaper. The need for plate making for industrial printing requires stable and high-speed printing plate making equipment. At present, the high-speed printing plate-making equipment promoted in China all comes from foreign advanced computer-to-plate CTP equipment. The high-speed CTP equipment in foreign countries currently monopolizes the high-speed plate-making market of the whole printing industry. This article will introduce you to Hanguang Aipu zinc oxide plate-making machine. . 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 replacing the plate with 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 being published, 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 process, in addition to direct illumination, there are scattered and refracted light, and the loss of light energy is relatively large. The laser light source of the laser plate making system is mostly monochromatic light. Generally, one wavelength or a range of wavelength is selected. This is the laser. The advanced position of the plate making machine. The unprocessed plate material means that the plate material can be printed on the machine after exposure and imaging on the direct plate making equipment without any subsequent processing steps. In terms of plate making, the process-free plates fall into two categories: process-free plates for DI (on-board direct imaging) presses and plates for exposure imaging on CTP platesetters. The process-free CTP plate improves production efficiency, eliminates chemical development, reduces the amount of energy consumed during exposure, reduces overall plate making costs, shortens the plate making process cycle, and has an advantage in today's increasingly emphasis on environmental protection— It is more obvious to the environment without pollution.
