TELEVISION LABORATORY PRACTICE 113 saying that the sprocket on which the films are printed must be cut to the highest degree of mechanical perfection possible. Unless all these factors of shrinkage and curl happen exactly to match with each other and the design of the sprocket, it is possible to secure better definition on prints made on a step printer, in which each frame is printed separately, and in which the negative and positive films are held in tight contact during exposure. The other main factor, in securing high definition, is the maximum resolving power of the positive film used. It has been remarked that if this resolving power is greater than that of the television system the other factors are immaterial. It is not believed that this is the fact, but that all of the definition possible should be saved in each of the steps necessary in bringing a motion picture to the television screen. Some of the prints shown were made on continuous-type printers and others were made on highest definition step-type printers. Some prints on each type printer were made on fine-grain release positive, and some were made on fine-grain duplicating positive, which has the highest resolving power of the commercially available motion picture films. This film also has the advantage of producing excellent quality when developed in the manner that these prints were made, that is, to a gamma of approximately 2.10, producing a good tone range on varying types of scenes.
