Abstract

A control negative for use in setting up exposure conditions for three colors in a photo-printer contains a mosaic pattern in a frame. The mosaic pattern is constituted of a plurality of segments of different densities and sizes. The segments are arranged such that the same area transmittance density can be obtained when density values are measured from different areas of the frame. The control negative is useful for different type photo-printers having different photometric areas for measuring the area transmittance density of the control negative.
