Abstract
An apparatus and method for vacuum printing inks onto a substrate in which the printing screen is mounted in a pivotable screen holder. The substrate is positioned on a printing platen and adhered to the platen during the printing operation by a vacuum hold-down system. The platen rests upon a product carrier which may be moved in a direction normal to the surface of the printing platen in order to adjust the spacing between the substrate and printing screen. The printing screen may be registered with the substrate by adjusting the position of the screen holder along two axes defining the screen plane and about a third axis normal to the screen plane. During printing the screen is deflected into contact with the substrate by a vacuum hold-down system. The system is configured to minimize the volume of air which must be evacuated during the printing operation.
