Pe and All,
I don`t know why I never thought to ask this befor now. I used to formulate screen printable, photoimageable masks for various industrial aplications. I know that, with the right rheology and surfactants, liquids can be very nicely screen printed onto just about anything. Thickness can be controled by screen mesh. I do not see why virtualy any of the emulsions discussed here or on The Light Farm could not be very nicely coated using this very old technolog. It would be less messy and more conservative of emulsion than blade or rod coating. What say you,PE?
