ABSTRACT:
The image dot gain that normally occurs in a printing press is controllably simulated as a separate step in the process of producing accurate color proofs. The simulation is attained by placing a diffuser plate between a high-intensity light source and a color-separated image master along with its corresponding image receptor. By varying the position of the diffuser plate the percentage of image dot gain is accurately controlled as an independent variable without the need to alter the exposure time.
