Silkscreen as a Masking Layer?
Can silkscreen effectively be used as an additional mask layer? For instance, if a negative silkscreen image is used it would coat an entire board except where the printed reference designators are located. The possible benefits are increased electrical insulation and resistance to chemical and mechanical damage. Has anyone ever done this before?

Because
you're re-purposing the material from Marking feature to Insulator
function, you might first check with UL (presuming the end-product performs to
UL).
