Toned prints only.

On the same rotary printer, the duplicate negative is printed onto the colour print film at a setting of the light valves needed to produce the tone colour required. Generally little or no scene-to-scene grading is required if the original was a graded print and the duplicate negative procedure was well set up and was exposed at a single light setting [i.e. was a one-light duplicate]. Some trial and error may be needed to achieve this or the negative can be scanned in a video analyser. If scene-to-scene grading is required then the ratio of the R, G and B setting must remain the same throughout the sequence. Even so grading by this technique is not advised as the colour does change slightly from scene to scene. On processing, the image will be a monochrome of the colour selected with the unexposed areas remaining white.
