- The original post described our (too) cumbersome procedure for obtaining
- color slides from TeX on a Mirus (non-postscript) film printer:
-
- 1. save the file as Illustrator 88 Postcript
- 2. import into Adobe Photoshop, which renders the PS
-
- 3. apply a color lookup table (a different table is needed for each
- foreground color used)
-
-
- All the proposed solutions were based on the color extensions (\specials)
-
- in dvips, and all but one involve spending money:
-
- 1. get a PostScript film printer and use dvips (which supports \specials
- that allow you to set the background and foreground colors).
-
- 2. use dvips with an external PostScript rasterizer such as Ghostscript
- (free), Freedom of Press (Color Age Inc., tel.: 800.873.4367(US),
- 508.667.8585), TScript (email: 47146958@mcimail.com, tel.: 617.734.9700),
- Professional Output Manager (Visual Business Systems, tel.: 404.956.0325(US)
- 0753.821234(UK)), Magic RIP (Knowlege Software, tel. 914.762.7667). I
- contacted Color Age and the maker of TScript. Neither vendor was
-
- familiar with the BSR TeX fonts so could not assure me that their
- software would work with these fonts.
-
-
- Since Ghostscript is free and runs reliably, I have tried it. Unfortunately,
- the font quality suffers. One suggestion was to render the slide at a high
- resolution and reduce the size. This is not very practical--Adobe Photoshop
- uses fonts rendered at 4x the desired resolution to get 16 levels of grey.
-
- Doing this on a full page creates very large files. Lines that TeX
- renders at one pixel wide are converted to grey in the reduced image.
- Thus it appears that anti-aliasing should be applied to the font
- bitmaps.
-
- Some time ago we discussed support for Illustrator PostScript with
- Blue Sky Research (makers of TeXtures), and were told they were considering
- dropping this option in favor of a generic EPS option (what dvips already
- has), but certainly were not interested in extending their support to Adobe
- Illustrator 3 and color.
-
- It is worth remarking that the anti-aliasing in Photoshop is based on using
- Adobe Type Manager to provide font bitmaps at 2x, 3x, or 4x the desired
- resolution. In principle, anti-aliased color fonts could be obtained from
- TeX pk fonts, but in practical terms it appears that PostScript fonts are
- more likely to work with existing tools.
-
- An Adobe Illustrator output option would be a very useful extension to
-
- to dvips. Adobe provided good documentation for earlier versions of
- Adobe Illustrator file formats, but has not released the current
-
- format. Many drawing packages can import Illustrator file formats, or
- can place Illustrator format files using a generic EPS mechanism. This
- would simplify the use of TeX in preparing illustrations, particularly
-
- color illustrations.
