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. The temperature is high, the fluidity of the ink is increased, 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. In order to achieve the best printing results, the printing shop is best suited to control the temperature at 22 ~ 25 °C.
