Digital Simulation of Prepress Proofing Systems

During the 1930s and 1940s a number of light reflection models were proposed and validated with experimental data. Of particular note are the 2 flux model of Kubelka and Munk (1931) and the color reproduction model of Neugebauer (1937). The manual measurement and data processing capabilities available at the time these models were proposed were adequate to prove model validity. However, the time required to make the measurements and calculations for all but the simplest applications made the wide spread use of these models impractical. Most of the potential applications for these models had to wait some 30 to 50 years to be realized.
