Homebrew PCBs

I've always wanted to do silkscreen plotting with my HP plotter. However, I
don't know where to get an ink that will withstand the heat of soldering.
Anybody have any ideas?

Could an HP plotter be used to plot on a soldermask as well? What type of
ink could harden to withstand the temperatures but also flow through a
normal HP plotter pen?

perhaps with silkscreen printing ? ;-)

3 other ideas that spring to mind:

Plotter (multicolor, slow)
toner transfer (black, maybe slightly conductive)
various "transfer sheets" like t-shirt transfer
