Kyung-hwa and Yun-ho operate a small space called "Paper Room," where they run a risograph printing studio and showcase a variety of works for sale. As designers, they leverage their expertise to create diverse art books and regularly participate in book fairs. Risograph is an eco-friendly printing method that uses soybean oil and rice bran oil, allowing for vibrant colors and high saturation, as it prints one ink color at a time. This makes it particularly suitable for artists and graphic designers to produce their works. Recently, it has also become popular among independent publishers and individuals looking to create unique pieces. Their dream is to continue operating the printing studio even as they grow old in a rural village.
