A screen support in the form of a segmental collar for use in a screen stenciling operation. The collar segments are movable into engagement with at least the transverse marginal edges of a glass substrate for accurately locating the same relative to an overlying screen and for providing support for the screen, and especially the perforated pattern formed therein, to maintain the same in a flat, horizontal plane during the stenciling operation.
