The Influence of UV Light in Color Measurement

This paper is to study the influence of UV light in color measurement. Our research is based on an actual measuring experiment, in which IT8.7/3 (basic) was printed to paper with OBA and one without OBA and measured using two devices in two conditions: including UV light and excluding UV light. Experimental results show that UV light only affects colors on paper with OBA, and there will produce color difference between two measuring conditions on this kind paper, as well the effect of color shift due to UV is quite global, colors are shifting towards the blue direction. Experimental results also release that UV light affects colors near white and blue heavily and has slight influence to colors near yellow and black.
