[mod.computers.laser-printers] Mergenthaler font outlines/ EP86, EP88

Chris Warth inquires about the history of digital outline fonts.
Outlines comprising vectors or arcs and vectors began to be used
in digital CRT typesetting machines in the early to mid 1970s.
The extinct Suncomp was one such device, and the infamous MGD
Metroset another. The Metroset is well known because its arc & vector
outline technology was implemented in hardware and patented. The
patent is usually called the "Evans & Caswell" patent, after the
inventors. There were two issues, around 1976 and 1980 (sorry I don't
have my copy handy). It is infamous because Rockwell, parent of MGD,
sued Allied, parent of (Mergenthaler) Linotype over infringement.
The Linotron 202, introduced in 1978, used a vector outline font,
substantially the same as the later Omnitech font (both were or are
Linotype devices). Allied settled out of court, and is rumored to have
paid a substantial sum, even though many experts believed that the
Linotron vector outline did not infringe the arc & vector MGD hardware
method. Now, III, having bought all rights to the Metroset, is suing
Compugraphic over infringement by the CG8600 outline fonts. CG is
fighting it. 

Even before the Metroset, there were academic treatments of outline fonts.
Philippe Coueignoux, in his MIT Master's thesis in 1973, described an
outline font format, and further elaborated on even more compact font
encodings in his MIT doctoral dissertation of 1975.

in April. The Proceedings have previously been cited to this list.
EP88 is scheduled for Nice, France, in 1988, organized by Jacques Andre
of INRIA, Rennes.
