Affected by the impact of rising prices of raw materials, the printing industry in the country showed a downward trend such as a decline in total profit last year. The situation of low-end products surplus is more severe, but industrial development still has rigid demand. Relevant industry associations are willing to work with Hunan Province and Changsha City to support the development of Changsha printing industry from the aspects of dot-print layout, regional exploration and industrial integration of the national printing industry, and support and promote Changsha to build a printing industry in the central and western China. Regional Radiation Center, this article will introduce you to the characteristics of computer laser platesetter. 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 the end of 2014, the company launched a nano-green plate-making technology based on the world's top speed of 180 sheets / hour off the press platemaking prototype - NT220-131A, the device uses a series of advanced materials such as "marble + magnetic suspension motor + high precision grating" The technology has realized the high-speed of plate-making equipment, and can fully meet the requirements of the mainstream newspaper printing for the speed accuracy and stability of the plate-making equipment. The launch of this prototype fully demonstrates that the nano-green plate-making technology has the ability to occupy the high-end market of the newspaper industry. To build a national science and technology innovation center and build a contribution to the development of a highly sophisticated economic structure.
