Technical Field

[0001] The utility model relates to the technical field of monitoring equipment, in particular to a real-time monitoring device for the quality of printed products. Background Art

[0002] A printing press is an important machine used to print text and images. Its basic working principle is that the content to be printed is first made into a printing plate and then installed on the printing press. Then, ink is applied to the place where there are text and images on the printing plate manually or automatically, and finally directly or indirectly transferred to paper or other substrates, thereby reproducing the same printed matter as the printing plate. In addition, printing presses can also be classified according to the form of paper used, such as sheet-fed printing presses and web printing presses. At the same time, according to the number of ink colors used in the printing process, printing presses can be divided into monochrome printing presses, two-color printing presses, multi-color printing presses, etc. The invention and development of printing presses have played a vital role in the dissemination of human civilization and culture. With the advancement of science and technology, the performance of printing presses has also been continuously improved, which has greatly improved the quality and efficiency of printed products.
