Subject: [Homebrew_PCBs] Printing pcb patterns negative or positive


I use a Panasonic KX-P6500 laser printer for making prototype boards
with Dyna Art paper, which seems to work fairly well for me. However I
am thinking of trying to make some silk screens for small volume PCBs
and I think I need to be able to print a "positive" of my PCB pattern
onto transparency in order to make the silk screen.

By positive, I mean that the copper tracks will appear white when
printed on paper, and etched portions will be black. My PCB software
does the usual "negative" print - copper tracks are black, etched
areas white, but not the positive print.

I use Ivex Winboard for my PCBs, and to do this would require another
Ivex product costing $199.00.

However there may be drivers or other ways to do this, can anyone advise?

1. see if you can get an updated printer driver that will allow whit on black.

2. The old version of Pentalogix Viewmate had the capability of white on black printing as an option. The current version does not, but you might be able to write them to get an older version. It was a freeware gerber tool.
