QTR-Quadtone RIP

Another way that I end up using quite a bit is to change the
first value of the GLOP channel to 0. (This is on a mac
where you can edit the .quad files easily). You end up with
a small border around the image, but it doesn't try to
print the rest (blank) part of the page.

Only problem I am aware of here is if you have a 
large area of 0 value in the image, but that doesn't
happen often. If so you can adjust the output values in 
PS to prevent a 0 output value.
