In the past, the graduation design exhibition boards were all sprayed with photographic paper and mounted on KT board. The size is that the whole exhibition board is divided into several vertical boards, one meter two times two meters four. The color must be accurate, and the whole looks good. The board is flat if its quality is better. Before listening to the introduction of seniors and buddies, they all played in square venues. Needless to say, they all understand. The ps resolution map was originally 200- 150, and the price was played by the whole class, which was much cheaper than that of individuals. Let the monitor talk to them about the price.
