Hi,
I want use transparent film to print a PCB on it, but in negative.
(nets, pads, text etc. -black, no cooper- transparent). I was doing it with Orcad and this work good.
One man was doing PCB from this film for me.
Unfortunately, Protel I tried to use doesn?t seem to have such option.
What can I do?
plot it to Gerber file, and translate it to pcx and use other application to make negative and print?
print to file (I have HP5L) and use other program(I haven?t idea which?) to print in negative?
maybe make ALT+PRINTSCREEN and paste it to Paintbrush, make negative and print (I use Windows) ;-)
Any idea very welcome!
