At present, China's electromechanical products market is in a state of fierce competition, and industrial design faces great difficulties in the design of electromechanical products in China. Therefore, China's printing machinery enterprises are accelerating the merger and development, and some of the large-scale business models are slightly effective. If compared with the foreign high-tech printing industry, China's printing machinery should continue to make relevant. Printing machinery should pay attention to the following principles in our design: 1, the principle that color should be suitable for people Most of the color of printing machinery uses a large area of ​​small purity color layout, and then choose a small area of ​​high-purity color to make significant changes, use the intermediate color to grasp the transition, the color requirements are simple, most of the most suitable 2-3 colors However, the details and main functions should be embellished with eye-catching colors, and the color arrangement needs to take into account the company's own color requirements. 2, pay attention to the principle of safety The planning of printing machinery not only requires easy operation, but also people's safety. Therefore, the arrangement of the operation stage should be suitable for the size of human-machine functions, and should also follow the national safety standards and be reasonable according to its function. Planning and Design. 3. Human-machine comfort principle The control equipment of the printing machine must be designed according to the size of the user's body part. For the arrangement and size of each function key, it also needs to be considered from the physiological characteristics of the human body. It should be suitable for people's general habits, can be arranged according to certain rules, and the function key arrangement should be more convenient to identify its use. . The main body of the printing machine body mostly uses straight and flat styling symbols, which makes people have a simple feeling and is more conducive to the processing of the printing. Since most of the body uses sheet metal materials, this avoids certain links. The pollution that appears to the printing.
