A stencil printer for printing viscous material on a substrate, the stencil printer comprising: a frame; a stencil coupled to the frame; a print head, coupled to the frame, to deposit and print viscous material over the stencil; a lift table assembly configured to support the substrate in a transport position and a print position; and a conveyor system including a pair of rail members (28, 30) coupled to the frame, the pair of rail members (28, 30) extending through the frame and being configured to transport the substrate through the stencil printer, and for each rail member (28, 30), a lift tool assembly coupled to the rail member (28, 30), the lift tool assembly being configured to cooperate with the lift table assembly and to engage and support the substrate at a transport height and a print height, the lift tool assembly including a lifter portion, a main plate secured to the lifter portion, a clamping member coupled to the main plate, the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate, characterized in that the thin foil is configured to move vertically and horizontally, independent from the clamping member, between an engaged position, in which the thin foil is moved horizontally to extend over an edge of the substrate and vertically to engage a top surface of the clamping member, and a retracted position, in which the thin foil is moved horizontally away from the substrate and vertically toward the main plate. a frame; a stencil coupled to the frame; a print head, coupled to the frame, to deposit and print viscous material over the stencil; a lift table assembly configured to support the substrate in a transport position and a print position; and a conveyor system including a pair of rail members (28, 30) coupled to the frame, the pair of rail members (28, 30) extending through the frame and being configured to transport the substrate through the stencil printer, and for each rail member (28, 30), a lift tool assembly coupled to the rail member (28, 30), the lift tool assembly being configured to cooperate with the lift table assembly and to engage and support the substrate at a transport height and a print height, the lift tool assembly including a lifter portion, a main plate secured to the lifter portion, a clamping member coupled to the main plate, the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate, characterized in that the thin foil is configured to move vertically and horizontally, independent from the clamping member, between an engaged position, in which the thin foil is moved horizontally to extend over an edge of the substrate and vertically to engage a top surface of the clamping member, and a retracted position, in which the thin foil is moved horizontally away from the substrate and vertically toward the main plate. a lifter portion, a main plate secured to the lifter portion, a clamping member coupled to the main plate, the clamping member being configured to move horizontally between a substrate engaged position and a substrate disengaged position, and a thin foil coupled to the main plate,
