ABSTRACT:
An apparatus and method are provided for registration of screens used in ink transfer processes for the printing of patterns on substrates such as clothing and other articles. The apparatus includes a platen surface and registration members that are mounted for movement toward and away from opposite sides of the platen. A pair of the registration members are coupled so that they move in mirror image in relation to a fixed point on the platen. When the screen frame is positioned on the platen, the registration members are activated to move inwardly toward the fixed point on the platen to center the screen in relation to the fixed point. Artwork is applied to the screen in alignment with underlying indicia provided on the platen and the screen is then processed to form a stencil in the screen. The stenciled screen is then aligned on the printing machine using the same or different apparatus by contacting the screen with registration members at the same points of contact used when the screen was aligned for application of the artwork.
