[Inkscape-user] spot color

Hi all,

I've got a project set up in inkscape, designed for two color (green and black) spot color printing.

First I'm going to send a PDF to the printing service and ask if it will work for them.

But I'm guessing I may need to cut all the green stuff out of the black stuff for this to work, maybe provide two separate layers, one with the black shades, and one with the green shades.

Does it sound likely that I'll need to do this, and if so are there any easy ways to do so, other than a lot of path differencing? And perhaps making the green shapes larger so there's no white where they're supposed to be contiguous with the black?

Or is there some easy way around all this I'm overlooking?

Thanks, Terry
