This is an interesting printing experiment, and the concepts I chose were overlapping and hidden. As you know, overlap refers to making objects and pictures more complex. On the contrary, leather can make objects and pictures easier. Some of them overlap, and some passively overlap. After overlapping or covering them, I found an interesting part, that is, I can get new graphics. In this project, I collected many kinds of themes to try to create new letter forms, mainly using overlapping and hiding techniques to make fonts and symbols.
