This invention relates to an aligning structure for aligning pin-receiving holes on a screen frame used in screen printing relative to upright pins mounted on a pin bar. The aligning structure, includes a pair of plates clamped on the frame. A first plate has an upright-pin-receiving hole to slidably receive the upright pin. A second plate has an upright-pin-receiving hole substantially larger than the upright pin. If the upright pin is received by both upright-pin-receiving holes and the clamp is loosened, the two plates can slide relative to each other to reposition the upright-pin-receiving hole relative to the screen frame. Retightening the clamp maintains the new alignment.
