No, it's something entirely different.
The photoresist is for all intents and purposes just another laquer that  
dries by evaporation of solvent.

UV curing ink is polimerization because of UV light, not evaporation of  
solvent.
You could just use any solvent laquer instead of photoresist, and spare  
yourself the mess with exposure, IF you could print solvent laquer of this  
consistency in a continous layer.

It is not UV curing ink.

Maybe someone can get his hands on the stuff they use for rapid  
prototyping with lasers? It could be what we need.
