The CTP platesetter is Computer to Plate, a prepress device that is directly plated by a computer. CTP plate making is to use digital workflow to directly convert text and images into numbers and directly generate plates, eliminating the need for film material, artificial imposition process, semi-automatic or fully automatic printing process. Compared with traditional plate making, the biggest feature of CTP plate making is that it eliminates the step of filming. This article will introduce you to the traditional ps 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 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. This is a new type of rapid printing plate making technology that is non-photosensitive, non-polluting and low-cost. Its promotion and application will cause great changes in printing plate-making technology, and it is expected to solve the problem of pollution and resource waste in China's printing and plate-making industry, and improve the level of technological innovation and competitiveness of China's printing enterprises.
