Stephen,
This isn't exactly what you are doing and if familiar to you then  
perhaps someone else will say "Ah!" but, you can get a similar effect  
with image types other than PICT.  I often use a GIF image that is  
much bigger than what I want to print.  By scaling it (setting the  
height and  width )and setting the lockLoc property to keep it from  
resizing, you can then print it (since all those dots were squeezed  
into a smaller space) at a higher resolution, depending on how much  
you scaled it.  I usually end up making a separate screen version  
that has some antialiasing or whatnot and then swap for the other  
when it is time to print.
