Well, for thicker deposits we don't use a screen. We use laser etched stainless steel sheets about 0.004" thick. They are bonded to a mesh to hold them in the frame but the mesh is cut away from the printing areas.

These are typically used for PCB solder paste (we use them to print conductive epoxy onto polyester). The coating thickness is generally equal to the stencil thickness and a sharp edged stainless steel squeegee is used.

We get ours from here: http://www.tecan.co.uk/core/about/overview.php

Not sure how the rod will work - possibly a bit like a rounded off squeegee and deposit a little bit more onto the substrate. You could also try zero snap off distance as they do with textile printing.
