A Practical Projection Gaging Method for Visual Inspection of 16mm Release Prints

Maxwell A. Kerr

A 16mm projector with a special aperture plate is used as a projection gage for checking various print characteristics while viewing the projected film. This method enables checking of such factors as soundtrack centering and modulation of variable-area tracks; shrinkage and variations in width of film stock; blackness and freedom from scratches of septums on each side of the soundtrack; placement and opacity of the printed frame around the picture image; and percentage jump-and-weave in the projected picture, including the amount added by printing operations.
