Mokuhanga is a traditional form of Japanese printmaking. Moku translates to wood and hanga means "printed." The medium arrived in Japan during the eighth century for the use of copying Buddhist sutras. The medium did not become a popular art expression until the Edo Period (1603-1868). Mokuhanga is most similar to western-style woodblock printing but differs in a few distinct ways. First, it uses water-based inks rather than oil-based (so no hard chemicals). The ink is brushed directly onto the woodblock instead of being applied with a roller. The impression is made by force of the artist's hand using a barren. Lastly, the registration system allows for multiple blocks to line up evenly and is carved directly into the woodblock - this is called kento registration. Mokuhanga has been exciting more interest because the technique uses water-based inks, which is easier to clean-up without harsh chemicals making it more environmentally friendly. Also the use of a printing press is not necessary, this medium can be a more accessible way to create prints.
