Abstract
Apparatus and method for supporting master image sheets on supporting platens includes forming vacuum seals between sheets and platens and evacuating air from therebetween to retain the master image sheets against movements on the supporting platens. An image receiving layer such as a photosensitive printed circuit board is disposed between supporting platens that are, then evacuated to retain the opposite surfaces of the layer in contact with the master image sheets for parallax-free photographic exposure to light through the platens, with inherent alignment of images thus formed on the opposite surfaces of the layer.
