Digital BW, The Print

Steve,

the idea has been discussed before, but probably a long enough time ago to 
merit considering again. The problems are:
- how thin you have to make the coating to pass through the heads?
- given the necessary viscosity, how much of it do the heads put down to 
actually coat without having to slow them down?
- if the paper comes out very wet, will it get any marks from the printer 
mechanism? 
- how long does it take per print, compared to the speed (but messy setup) of 
a rod?
- what happens to the printer when the liquid dries in the head? will it be 
re-dissolved by more of the same or will it require that a solvent be run 
through - that won't harm the heads? And how will you see nozzle checks with  
a clear liquid?...


Nevertheless, it would be nice if it worked - better yet, if one could dedicate a 
single jet to coating and do it "in line" like offset printers do. Dream on.... (but, 
hey, if someone invents it I'll buy it!).
