The screen printing apparatus is characterized by a carriage having a substrate to be printed resting thereon and a frame member extending about the periphery of the carriage. A mesh screen having an emulsion layer is affixed to the screen and suspended over the substrate. The improvement comprising a pair of force absorbing members attached to the carriage in a space relationship to and on opposite sides of the substrate. A pair of rolling means are attached to opposite sides of a squeegee holder with each rolling means in registration with a respective force absorbing surface. A squeegee extends from a bottom surface of the squeegee holder intermediate the rolling means. As the squeegee holder is drawn across the screen each rolling means travels along a respective force absorbing member.
