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.

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