A screen printing frame (1) has a rigid outer frame (3, 4, 5, 6) and an inner frame (8, 9) which has only two sides to it. This inner frame has attached to it a mesh screen (7) which is also attached to two co-acting sides of the outer frame. Thus, when the two sides of the inner frame - which can be expanded - are moved outwardly towards the outer frame, the mesh screen is placed under tension. |
