Exploring the effects of color on laser paper for the first time, the uniqueness and versatility of laser technology have made it an indispensable part of contemporary design. In particular, the use of gradient color is incomparable to bronzing, and the brightness is like a three-dimensional pattern made of pieces of glass, showing infinite possibilities between light and shadow. Traditional foil stamping processes can often only be stamped in a single or predetermined color, limiting the flexibility of creation. Today, however, with advanced artwork design, it is easy to print a variety of metallic colors simply by changing colors, adding many new options and possibilities to design. This innovation has made the world of children's books even more colorful, and each book seems to invite young readers to explore imaginative stories. The diversity and rich colors of laser paper make the expression of creativity no longer limited, so that each work can resonate and inspire, and bring a new visual enjoyment to the audience.
