Printing: For a long time, printing must have a printing plate. The ink (or color material) on the printing plate can be transferred to the substrate only under the pressure. Therefore, people believe that the development of printing technology is the evolution of printing plates and pressure. However, in recent decades, especially in the last decade, due to the continuous expansion of electronic, laser, computer and other technologies to the printing field and the application of high-tech achievements in printing, traditional analog printing based on printing plates and pressure Challenges have been raised, and digital printing methods that do not require plates and pressures are endless.
Nowadays, people often refer to the design of originals, the processing of graphic information and the plate making as prepress processing, and the process of transferring the ink on the printing plates onto the substrates is called printing, so that the completion of a piece of printed matter needs to be prepressed. Printing, finishing and other processes.
