5 installation and commissioning of the machine
The installation and commissioning of the machine is an important part of ensuring the normal operation of the machine. If something goes wrong in this process, it will bring a series of problems to the subsequent operation and use, including the impact on the quality of the printed matter and the accuracy of the machine. Therefore, we must try our best to eliminate the possible problems in this area. stage. There are many factors involved in the installation and commissioning of the machine. A detailed analysis of these factors is given below.
5.1 Selection of printing shop
The printing environment is one of the eight major factors that affect the quality of printed products. The more exquisite printed products have higher requirements on the environment. The content of the printing environment mainly includes temperature, humidity and cleanliness. The temperature directly affects the fluidity of the ink. When the temperature is high, the fluidity of the ink increases, and it is easy to paste or imprint the ink. When the temperature is low, the ink may not be opened, resulting in a flower pattern. Humidity directly affects the size of paper electrostatic force. The higher the humidity, the more humid the electrostatic attraction is; the lower the humidity is, the drier the electrostatic attraction is. As the humidity increases, the deformation of the paper also increases. Therefore, we must take this into consideration when selecting the humidity. The degree of cleanliness directly affects the quality of the printed product, and the higher the accuracy of the printed matter, the higher the cleanliness of the printed environment. If the cleanliness is too low, the surface of the printing plate, blanket, and paper, and even the ink and fountain solution, will seep into the impurities and affect the transfer of the ink. In addition, the printing shop has noise requirements, if the noise floor is too strong or the possibility of noise is very high, plus the noise of the machine may exceed the specified noise standards. In addition to these problems mentioned above, the interaction between the units and processes should also be taken into account. A good printing environment should coordinate these factors to the best state. Some factors can be solved after the machine is installed, and some factors must be taken into consideration when building the workshop.
