Caflisch Script: a one-axis multiple master typeface

Multiple Master Typefaces
These new typefaces are called “multiple masters’’
because two or more sets of outlines, or master designs,
are integrated into each typeface. The master designs
determine the dynamic range of each design axis in a
typeface, and the PostScript language enables ondemand
interpolation, or generation of intermediate
variations, between the master designs. For example, a
light and a bold master design delineates the dynamic
range of possible font variations along the weight design
axis, and the user can interpolate variations anywhere
within this range. The particular design axes that comprise
each multiple master typeface are based on the
aesthetics and potential uses of that typeface; therefore,
the number of design axes and their ranges vary from
one multiple master typeface to another. Some of the
possible design axes include weight, width, style, and
optical size.
