Quoin and quoin key at the Nomadic Press

CUT TO THE CHASE

A set of quoins (shown here in a chase with a quoin key, furniture and a milled aluminum mounting block) is an indispensable tool in the lock-up of a printing form. Actually a simple pair of wedges, quoins are placed in both the x and y axes of the chase and, with the aid of the quoin key, they are tightened so that they literally wedge the printing form and the surrounding arrangement of furniture snugly into the metal frame (or chase).
