Mathematical Model for Typeface Measurement.

A mathematical model is developed for typeface measurement and its applications. The model is defined by x, y coordinates. It measures the letters vertically and horizontally and between lines. It also provides a framework for computerizing the print planning process and a formula for type design. Further, it generates the data necessary for prepress automation and estimates the product yield. The model can be applied to any measurable units in points or metric terms. An example of 300,000 characters is used to illustrate the validity of the model.
