Abstract :
A new approach to grayscale font generation improves on the fuzzy characters produced by existing methods by incorporating the expertise of type designers into rules for character-outline weight and phase control. The method we propose for synthesizing high-contrast grayscale characters relies on the set of visual rules that type designers have derived from their many years of manual design. We call our grayscaling method `perceptually tuned font generation´, because it is based on human perception-that of both the designer and the reader
