I have been coating close to 9 mils.
We tend to use a 120 or 140 mesh when we print our conductive silver ink. The printed surface is very smooth and actually has a texture very similar to emulsion on film. We use a machine coater to coat the stencil emulsion onto both sides of the mesh (although we sometimes use Capillex from Autotype). We usually end up with a printed thickness of around 8-10 microns. Perhaps two or more coats would be needed for an emulsion as 1 mil (or 1/1000") is a lot more than a micron. For a thicker print (of dielectric materials) we would go to a 79 or more course mesh and a thicker stencil. Unfortunately the course mesh will leave an impression in the ink/emulsion.

I was thinking that texture on a paper could be a feature to work with artistically whereas it would be un-anted in a film.
