This is the campus UC logo made by our group. It means the combination of leisure and campus. A cup of coffee is also a good idea when you are tired of studying. This is the first attempt to combine the UClogo with other information. It can be printed as a disposable coaster. We chose red as the color of the coaster in the studio. We first cut the big cardboard into squares, and then we typed out the model, we need to wait twenty minutes to print the model on a yellow card. Next, we adjusted the color because there is no ready-made color. We used three colors, WARM RED, RUB RED, BLACK, and the ratio of the three colors was 73.9:24.6:1.5. After we finished the color, we put the model and paper on an ancient printing machine and started making a coffee coaster. We printed very successfully, and the whole process of printing was exciting,and we decided to print 200 copies, each selling for $1.
