Abstract

Typescript specimens from several printwheels of different manufacture were examined to ascertain how the manufacturing process may influence type design. Among the parameters considered were the composition, molding process, sequence, and physical design of the printwheel. It was found that each parameter may affect modifications in a typefont. These variances in type design may cause difficulties in the classification of printwheel type styles.
