A computer-driven printing system automatically adjusts inter-character spacing to account for the different visual effects that font scaling has on different ordered character pairs. The adjustment A(S, Xj, Xk) for a given size s and character pair (Xj, Xk) is computed from the formula:A(s, Xj, Xk)=C1(Xj, Xk)+C2(Xj,Xk) s-+E,fra 1/2+EE ,where C1 and C2 are constants with respect to s but are not in general independent of (Xj, Xk). The constants C1 and C2 are determined by a procedure that is equivalent to finding A manually at more than one size s and solving the resulting equations simultaneously.
