Hz program [Hermann Zapf] Hz-program was a proprietary, patented typographic composition computer program, created by German typeface designer Hermann Zapf in 1988 based on work he carried out first at Harvard University and then at the Rochester Institute of Technology. The goal of this program was to produce the perfect grey type area without the rivers and holes of too-wide word spacing. Little is known about the composition algorithm created by Zapf and implemented in Hz-program. It is partly based on a typographically acceptable expansion or condensing of letters, called scaling, accorduibng to Zapf. Inside Hz is also a kerning program, that computes negative and in some cases positive kerning adjustments for glyph pairs on the fly. The Hz-program was patented by URW (the patent expired in July 2010). Later, it was acquired by Adobe Systems for inclusion as the composition engine in Adobe InDesign application. It is not known if the Hz-program algorithm is still included in the latest releases of InDesign.

Electronic Publishing, Vol. 6(3), 283-288, September 1993. InDesign, the hz-program and Gutenberg's secret (Torbjørn Eng, 2007). In this web article, Eng writes: It is claimed that the option in Adobe InDesign to vary glyph (character) widths as a part of the justification is based on the composition technique of Gutenberg in his 42-line Bible (1455), and on the font designer Hermann Zapf's hz-program (with URW, 1992). An examination of this claim raises serious doubts about the validity of the references to these highly respected authorities.
