Positive Mechanical Transfer. If you change your resist chemistry,
you can also use a litho negative, which they shoot on the same
camera and usually costs less. I, however, use PMTs.

Look under "Lithographic Negatives" in the yello pages.

I pay $14.75 for a 50% shot, 8X10 final size PMT
If you have a very small 1:1 shot, and are REAL good at begging, you
can sometimes get them to stick your art into the wasted edge of
someone elses large job. The material would have been thrown away
anyway.

Everyone should understand that the litho camera will faithfully
reproduce your artwork, AND EVERY DEFECT ON IT. I almost never
work less than 2X final size and sometimes work at 4X for real
fine line work. Tripple check your artwork fcr problems like
hairs, smears, etc.
