Acutance of Plus-X film was examined as a function of development time, temperature, and sulfite content. Five levels of each factor were used with equal increments respectively. Method of printing knife-edge targets and noting the extent of edge-effects was also sought for. Acutance was found to increase with increasing development time and temperature but decreased when the sulfite content of the developer exceeded the recommended amount.
