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 -- gerry pratt -- workstation support -- university of keele email: gerry@seq1.keele.ac.uk * tel: 0782 621111 x 3290 "these opinions are mine, mine, mine....ALL MINE I TELL YOU!"

What kind of printer are you using? I tried some text on the local
LaserWriter IINTX and it looks just fine. I didn't try it on a
write white printer.

Try something like this as a first approximation:

Fiddle with the value before the setlinewidth operator to get
the results you want.
