From: Cal Jackson <CALVIN@CIT-20.ARPA> This is an inquiry about the compatibility of Imagen printing systems with TROFF produced documents in the UNIX environment. Specifically, where the type faces for the TROFF produced document were selected from the Berkeley Font Catalog. We use four printers: Versatec (200 dpi), Imagen (240 dpi), Imagen (300 dpi), and HP (300 dpi). (Also, preview devices at ~100 dpi are used.) We use three document composers: TeX, TROFF, and SCRIBE. For 200 dpi print devices, we have type faces due to UNIX (TROFF), SCRIBE, and TeX. For other resolutions, we have only the TeX CM (AM) type face. We "observe" that the Imagen support software maps some of the UNIX type styles (Hershey roman, italic, bold, and sans serif) onto the CM fonts. (Mysteriously, the math also gets set.) Is our observation correct? Also, is anyone printing all (styles and sizes) the fonts in the Berkeley Font Catalog on 240 and 300 dpi Imagen systems? If so, how? -------

From: hplabs!bragvax!david@Berkeley You seem to be confused about the Imagen troff support software. The catdvi program reads a "catab" file to determine which glyph from which "RST" format font file to assign to each of the 512 CAT characters. You can look at the "chartab.txt" file to see the exact mapping, but in general the Roman font maps to "cmr", Italic to "cmti" and "cmi", Bold to "cmb", and Special to "cmsy" and "cmathx". The standard catab does not include any sans serif characters. In order to access other Imagen fonts from a troff document, you have to make your own catab with the charmap utility. Unfortunately, Imagen refuses to provide any documentation on this process. If you want to use the Berkeley fonts, you will have to convert them to RST format (good luck), then make a new catab. By the way, Imagen recommends buying ditroff and their Impress postprocessor if you want to use other fonts. The package costs $1K for the postprocessor and some mysterious amount for the ditroff binary license (or $4K for the source license from AT&T, probably less for a school).
