The purpose is to explore the unique expressions of graphic design and convey the fun of visual experience to students.

In general printed matter, the image is reproduced by the difference in the density of halftone dots. However, in these works, the entire screen is composed of only 40% halftone dots. Therefore, if you take off your glasses or look at it from a distance, it will become a flat gray surface, and in theory the motif will not be visible.

In reality, the motif appears vaguely due to the texture gradient of the dots. Students familiar with digital on-screen design were able to learn about printing principles and visual mechanisms.
