ABSTRACT:
The method of making color separations from masked colored transparencies which involves exposure of the transparency from separate light sources each having different colored light outputs with limited spectral band widths and from light sources which approach in size the physical size of the transparency to significantly reduce the power requirements for the light sources. The improved apparatus includes means for mounting a plurality of such light sources within a copy holder or associated therewith to selectively direct light having energy emission over the limited spectral band width onto the masked transparencies for exposing the films sequentially in the making of color separations.
