Production of second-generation camera-original control tool photographs via photography of digitally generated transparency of a computer-originated image

A method for making product second-generation reproduction images having colors of specified chromatic values comprising the steps of:

• a. specifying calibration signal values representing the signal value range of a digital imaging means;
