The structure has a predetermined Q-height for ultimate affixation on opposed sides of the screening area by means of an inventive fixture and process, which is characterized by Q-height spacers. The structure has a base with a hardened layer of cement of selected thickness thereon for affixing the structure to the faceplate, and on an opposed side, a surface for receiving and securing the mask.
