Abstract
Sgraffito is a technique for decoration where a surface is scratched away to reveal another underneath. This ancient
technique can be extended by applying multiple layers of paint on fiberboard and using a variety of tools to scratch
through the layers, resulting in richly textured pieces. Aspects of the sgraffito technique may be modeled digitally.
In particular, images may be digitally processed using a small color palette to simulate the small palette used when
applying the sgraffito technique using pigments. Post-processing involves smoothing out the digital images, since
isolated pixels in a digital image are details too fine to be obtained using handheld tools.
