Interesting. What’s the particular application that would warrant that? I’m asking because conformal coating could be applied easier.
Also, do. you plan to stick to a certain resin, or do you have a little test setup to adjust for e. g. differences in viscosity?

Conformal coating with a silk screen never worked well for me. There were always visible creases and uniformity issues.
I also want to have a consistent layer thickness because the intention is to start with a white layer and on top of that a green layer. I will use a laser engraver to remove part of the green layer to expose white again to make the silkscreen layer.
A spincoater ensures the coating is always exactly the same which is good for laser ablation.
