Hi Steve,

The UV inks are an exciting development. UV-cure technology seems like near-magic to me. I use a UV-curable adhesive to make glass emulsion wells. [/I]

That's a very interesting.
As an aside, photopolymers (hydrophilic or hydrophobic) based on free radical polymerization, may actually provide improved adherence to a great many kinds of substrates. Free radical formation seems to be the principal reason why corona treatment "works".
