Further evaluation of methods for producing desired colors on CRT monitors

Three experiments were performed to evaluate methods for predicting the luminances and chromaticity coordinates produced by color CRT monitors, given known inputs. Linear and logarithmic versions of PLCC and PLVC, plus Berns, Motta, and Gorzynski's power function, were tested. Estimates are provided for the number of CRT measurement points needed to maximize each method's predictive accuracy. Correcting for unintended light from the monitor is shown to improve accuracy substantially for a case involving a seemingly small amount of light. Berns et al.'s characterization technique, which involves measuring the monitor's neutral point, is shown to yield the same accuracy as conventional characterization while reducing the number of measurements required, and to yield improved accuracy when correction for unintended light is needed but impractical. The accuracies of the predictive methods are compared and recommendations for their use are provided. © 2000 John Wiley & Sons, Inc. Col Res Appl, 25, 90–104, 2000
