The high-speed gravure printing machine can be opened to 160m/min under normal conditions, and the viscosity of the ink is about 16s, but the viscosity of the ink used for gravure proofing should be adjusted to about 20s. The slow speed of the proofing, the high viscosity of the ink and the low hardness of the rubber on the impression cylinder are all conducive to the full transfer of the ink to the substrate. This article will introduce you to the cardboard proofing machine.
In recent years, digital proofing technology has become a hot technology in the prepress field. The digital proofing machine proofing refers to the use of a color printer to directly output the page data made by the color desktop system in the form of a sample without using any simulation method, and to check the quality of the image page before printing, and the printing process and the user can use it as a sample. Refer to the means of signing and printing.
Computer-to-plate technology and digital printing have developed rapidly in recent years. At the same time, it has also opened up the application range of digital proofing. It is based on the digital publishing and printing system. According to the corresponding production standards and specifications, the page map in the publishing and printing production process. The text information is properly processed, and through the color management, the conversion relationship between the digital proof paper and the printer profile is established, so that the proof matching problem with the proof color is also solved.
However, in actual operation, because there are some factors in the proofing system itself, such as stability, measurement error, etc., it is impossible to achieve no chromatic aberration at all. Therefore, it is necessary to correct and optimize the digital proofing color management so that the color difference is maintained within an appropriate range as much as possible.
