There are several solutions.
1) Print artwork files to disk as HPGL and use PrintGL
<
http://www.concentric.net/~ravitz/> to do what you will with them. This
is the method I use.
2) Print artwork files to disk as Gerber and use one of the freebie Gerber
viewers to print the file. I ∗think∗ they can do a negative but I'm not
sure. Look for GCprevue from <www.graphicode.com> or ViewMate
<www.lavenir.com> i
I think highly of Cary Ravitz's PrintGL - so much so that I purchased a
licence several years ago. I use it several times each week. Do note that
the software is not crippled in any way - it works the same if you pay for
it or not. Only your karma knows the difference!
