Thanks for the feedback.
I'm asking as I'm curious as to which would waste less emulsion, a paint brush applicator or a fine screen process? As a painter, I see how much material a good brush will pick-up, lay-down and what washes out in the clean-up.
A screen used to coat a number of sheets at one time would seem to be a better choice but real world experience is often different than theory.
While I'm asking questions, does anyone here think an inkjet could be modified to lay-down emulsion?
