Ed - Have you thought of printing the target on a larger sized sheet of 
paper? You could then upsize the target in PS or in Qimage (be careful not 
to use any sharpening if you upsize in Qimage!) and your patches should be 
as big as you like.

Alternatively, you could divide the target into two parts in PS, upsize 
each part, and print each upsized part on a separate sheet of paper. This 
sounds complex, and it is, a little. You'd be less likely to make reading 
errors (read the wrong patch) if you trimmed each of the two parts and 
tapen the two together, so you'd have one very large target, with all its 
numbers and letters in the same order as the original.

Best of all, IMO, is to just persist with the targets as they are. As 
others have written, they're not that difficult to read once you get a 
little bit of practice.
