What I neglected to mention was that this information was old; I
learnt it perhaps ten years ago.  The extra color (switching
spelling systems will drive me crazy yet!) was brown; apparently
whatever processes were used did not reproduce browns very well.

In article <93@eps2.UUCP> jon@eps2.UUCP (Jonathan Hue) describes
a laser scanning process that produces `four color separations
(cyan, magenta, yellow and black)'.  Clearly this is a newer
process that has taken over now that scanning lasers are cheap.
I stand corrected.

(We now return to your regularly scheduled news :-) .)
