Pcb negative print out

I just wonder if it is possible to print negative copper views?
My computer is ocupied by kids at the moment…
I have negative photo resist…
I think the lines becomes better.

Yes (and, No).

You can export a Production SVG from Fritzing. Then, in a photo editor, such as Inkscape, change the colors. You can group select… you know how to mess with that sort of thing (if not, check out some YouTube tutorials on Inkscape… for color changing)
Here’s an example:

Or use imagemagic to swap colors…
If it only contains black and white…

what is image magic?

ImageMagick

interesting i’ll take a look at that one.
but i already have inkscape and affinity designer 2. they probably do a similar thing. i’m just looking for the a faster way way to invert an svg and send it to my laser printer. seems like a simple thing, but it is becoming more headache that it should be lol

As always google is your friend a search for “inkscape invert black and white” turns up

which indicates there is an extension that will do this. You would need to try it to see if it works for you though.
