ABSTRACT:
An off-contact setup device is provided for a screen printing type machine. The setup device includes a frame that releasably clamps onto a levelled image pallet of the screen printing machine. The height of the setup frame relative to the pallet surface is adjusted. This height is calibrated to a desired off-contact distance between a printing screen and the substrate to be printed (which is positioned on the pallet during printing). The frame holding arm of the printing machine, which is used to support the screen printing frame, is brought into position and secured to the setup frame. The height and level adjustments for the screen frame holding assembly are then fixed so as to conform to the position of the setup frame on the pallet. This process is repeated for all stations on the printing machine. Thus, the relative distance between all pallets and the screen printing frames attached to the holding assemblies are set to be the same, providing a consistent printing operation.
