In this paper, we describe a method of scratched-look expression of our calligraphy system. Scratched-look has very various patterns. Our system makes acratched-look patterns by using fractals. In this system, a scratched-look expression is expressed by white points which are plotted with affine transformations on a calligraphy character. Thus, the system realizes scratched-look patterns which resemble real calligraphy scratched-look pattterns. More-over, the system evaluates user writing speed and pen pressure, and decides the degree of scratchiness(s_degree). The density of plotted points corresponds to s_degree, the shade of scratchiness is expressed. All 4 types of scratched-look patterns which are made in this system are close to real calligraphy scratched-look. Furthermore, besides visusal evaluation, fractal dimensions of scratched-look patterns in both the system and real calligraphy are evaluated and compared, these results reveal that fractal dimension is similar value.
