Reduction woodcut print is a branch of woodcut, also known as offset color woodcut. It originated in Simao, Yunnan in the early 1980s, with artists such as Zheng Xu, Wei Qicong, and He Kun creating a new technique different from other woodcut methods. This technique breaks through the traditional process and aesthetic view of offset color woodcut, which is to concentrate all color plates of a painting on one plate, and use the method of carving and printing step by step to complete it, so it can also be called "reduction printing". Because the process of creating this kind of oil woodcut printing is a natural destruction process that cannot be reversed, once the work is completed, the original plate cannot be printed again, so it is usually called out-of-print offset color woodcut printing, which is different from the traditional divided printing method. Out-of-print woodcuts can not only be depicted in detail but also be highly summarized with strong expressive power.
