Yunnan out-of-print woodcuts are special art form of woodcuts. They encompass Chinese traditional culture

and they are a typical representative of artistic characteristic of Yunnan local minorities

which has high artistic value. The digital synthesis of Yunnan out-of-print woodcuts not only solved “out-of-print” woodcuts

but also reserved and inherited this kind of Chinese traditional culture. According to the actual process of Yunnan out-of-print woodcuts

a technique of interactive digital synthesis of Yunnan out-of-print woodcuts is proposed. The preliminary work of the research was collecting nicks from real woodcuts images

and nick libraries were structured with them. In the simulation process of print

we initially used the color that was achieved via color clustering algorithm to layer the image. We then used a painting brush to render the nicks on the image to simulate engraving. After coloring each layer

which simulates printing

we rendered the abstract edge to enhance the contours. Compared with the results of Photoshop woodcut filter

our synthesized results are more realistic and satisfying. The method simulates the actual process of Yunnan out-of-print woodcuts and fills in the gaps of NPR(non-photo realistic rendering) in the area of Yunnan out-of-print woodcuts.
