Yup. Something like that. Never quite works perfectly. I was wondering how 
velum (Or similar) would work being run through an ink jet. But this is why 
I mentioned printing 2, then sticking them together.

Yeah. That's the thing isn't it. I've spent so much time pissing about with 
trying to get a reliable method of doing this stuff that I've all but given 
up and just taken the "Bulgarian option."

But I had another really REALLY!!! crazy thought though.

Since CRT video monitors are a dime a dozen these days, why not get a 
big-ol' flat screen 19" or 21" monitor, mount it so that you can stick a 
pre-sensitized board under it, or to it's face, and then with a bit of size 
adjusting, use that to expose the board directly? I think I recall some 
other photographic process that basically did it that way. Can't think what 
it was now though. But it's just crazy enough that it might actually work. 
Vector scan anyone?

Be absolutely Icebox.
