      Actually, Harold, I agree: the maths, such as it was, simply tells me that
      you'd need to take off less for the big sizes (above 18pt) and more for the
      smaller sizes (8pt to 18pt).

      As an alternative to p-optimising the font itself, could one not use the
      standard font and slightly (but how slightly?) over-expose the plate? I've
      never used PP, so please look tolerantly on a suggestion that probably shows
      a lamentable ignorance of the technology. I know that when we were setting
      books for offset we'd occasionally get the service bureau to beef up the
      type by changing a setting on the imagesetter.

        That's so embarassing. And to think that I have a minor
        in Math... A micron is 10^-6 *meters*, not centimeters. :-/

        This is great news. Dwiggins, Justin, and
        now that guy are all in the same ballpark.
