RIDT (Raster Imaging and Digital Typography) is the title of a series of conferences on electronic publishing that were organized in the 1980s and 1990s, when digital typography emerged from research laboratories and became widely used. State-of-the-art research, techniques, and solutions in digital typography and image rasterization were presented in these conferences.
RIDT ’91 took place in Boston, Massachusetts, October 14-16, 1991. The conference chair was Robert A. Morris and vice-char was Roger D. Hersch. The day before the technical presentations, Jacobo Valdes gave a tutorial on type rasterization, and Kris Holmes and Hans Ed. Meier gave a tutorial on digital type design. As in their professional design and teaching, Holmes and Meier first demonstrated the historical handwriting that gave rise to our modern typographic forms, explaining that digital type, like photo and metal type before it, carries on a much older tradition in which our modern letters were developed through centuries of hand-written practice and critical reading. After handwritten demonstration and practice, Holmes and Meier presented methods of digital design.
The technical papers of RIDT ’91 were published as Raster Imaging and Digital Typography II by Cambridge University Press, 1991. The text was composed in the Lucida Bright and Math fonts designed by Kris Holmes and Charles Bigelow. The tutorials, however, were not published. Here are a few examples from the Holmes and Meier tutorial.
