Gerber is the way out of Protel. Create the gerber files and print them with a gerber program. Protel
doesn't have any native support built in for gerbers and most other PCB packages don't either. Strange but
true. Camtastic comes with Protel 99SE but I prefer Gerbtool. CAM 350 is another good one. CamCad is
yet another one that also will do a lot of file conversions between various board and schematic formats.
There are some freeware gerber programs out there but I've never done much with any of those.
Oh, and if you are going to use photo resist boards, click the "mirror" box on your layers in Protel, then when
you export the gerber and print it, you can lay the ink or toner side down on the board surface for the exposure
stage.

Subject: Re: [Homebrew_PCBs] inverting
Hi:
I was wondering if anyone knew how to invert a printed circuit board image? I am using protel 99se and I can print a positive of the image just fine but I am trying to find a way to invert this image turning it into a negative. Protel allows you to export an image as a windows media file but when I do this and take it into an image editing program such as paint much resolution is lost. I am trying very hard to avoid the process of printing, scanning and reprinting. Any suggestions would be greatly apprecitated!
Thanks,
Randy Knutson
