1950 SYNTHETIC COLOR-FORMING BINDERS 465 the various dyes and their contributions to a neutral density of 1.0 are given in Fig. 6. 400 500 6OO WAVELENGTH IN MILLIMICRONS 700 Fig. 6. Spectral characteristics of component dyes and resulting neutral. PRINTING Du PONT TYPE 275 COLOR FILM To make pictures on Du Pont Type 275 Color Film, Release Positive, three-color separation negatives must be printed onto the one release film in such manner that the positive image of each color separation is recorded only in the proper dye-generating layer. Naturally the three dye images in each frame must be superimposed in register. Because of the complex nature of the stock, only limited variation of contrast can be achieved in processing, so the primary control of contrast and balance lies in adjusting the contrast of the negatives. These requirements mean, for the present, that Type 275 must be printed in a register printer from three black-and-white separation negatives, each printing exposure being made through a narrow-pass filter so that the image will be confined to the appropriate subtractive color. Any black-and-white three-color separation negatives may be used to print Type 275 provided they have the following characteristics : 1. Proper color separation ; 3. Good register; 2. Correct orientation for 4. Acceptable sharpness; same-side printing; 5. Reasonably fine grain; 6. Appropriate contrast.
