This revolutionary digital font format, developed from Adobe Systems is extension of PostScript Type 1. The Multiple Master fonts are Type 1 font programs that include two or more "master" fonts within a single font file. They allow users to interpolate many intermediate "instances" of the typeface. The Multiple Master fonts have one or more design "axes", such as weight, width, optical size, and style. Multiple Master typefaces add new dimensions to typographic control and unprecedented flexibility - the user can generate a very large number of variations from a single font.
The Multiple Master fonts from HermesSOFT Type Library make it possible for users to create fonts of varying weights and widths without any distortion of the letter form.
