An apparatus for preparing a screen for screen printing comprising:
- a housing having a screen bed for placement of a pre-stretched, ultraviolet sensitive emulsion coated screen in a rectangular frame, the frame including a first end, a second end opposing the first end, a first side and a second side opposing the first side;
- a registration system attached to the screen bed for positioning the frame, the registration system including a first retainer for contacting a first end of the frame, a second retainer perpendicular to the first retainer for contacting a side of the frame perpendicular to the first end, and an adjustable biasing mechanism having a vertical planar wall portion for contacting the second end of the frame, wherein the biasing mechanism includes a spring and wherein the vertical planar wall portion includes a horizontal planar wall portion connected to a top edge of the vertical planar wall portion, the horizontal planar wall portion configured to extend outward over the second end of the frame.
