Applying Video Technology to Color Measurement for the Graphic Arts Industry

Video cameras are proliferating in the graphic arts industry for various inspection and control functions. When this technology is used for color measurement, unexpected sources of noise will become evident which will degrade measurement accuracy. This paper will propose a threshold for acceptable measurement accuracy given a possible color control application. Based on this threshold, measurement variation with respect to time, position and neighborhood will be explored. Tests will be introduced to identify these noise sources without the use of sophisticated lab equipment. Recommendations will be provided to improve the overall system performance.
