Practical method for appearance match between soft copy and hard copy

CRT monitors are often used as a soft proofing device for the hard copy image output. However, what the user sees on the monitor does not match its output, even if the monitor and the output device are calibrated with CIE/XYZ or CIE/L*a*b*. This is especially obvious when correlated color temperature (CCT) of CRT monitor's white point significantly differs from ambient light. In a typical office environment, one uses a computer graphic monitor having a CCT of 9300K in a room of white

The visual experiments were performed on the effect of the ambient lighting. Practical method for soft copy color reproduction that matches to the hard copy image in appearance is presented in this paper. This method is fundamentally based on a simple von Kries' adaptation model and takes into account of the human visual system's "partial adaptation" and "contrast matching".
