I have a generated som PostScript to print labels over a pale gray
halftone image. The font sizes are 12 point or more and the contrast
between the black letters and the gray background is OK but
most of the text is unreadable. The halftoning ruins the outline of
each character, whatever the point size, so it is unreadable.
Is there a solution to this like a font definition that produces
a white character slightly larger first before printing the letter.
Or any other suggestions welcome.

cheers,
gerry
