Homebrew PCBs

Thanks Larry for a fast reply.
Since it is negative photo resist how do you create the negative image?
Normally the PCB programs gives a positive image (showing traces) but it
needs to be reversed before using with negative artwork.
I a very long time ago used to use Kodak's KPR but then switched to
pre-coated positive resist.
I have a long time ago made reversing copies but what do you do today?

It is a clever idea to use the FoodSaver vacuum bags.

JetStar transparencies used for silk screen artwork are what I use
primarily, printed on an Epson Artisan 810. I then seal the artwork against
the board for gap elimination in a vacuum heat-sealed bag (FoodSaver).
