The Effect of Fluorescence in Paper on Color Change of Printed Samples Using a Laboratory Color Printer

In the printing process, paper and its characteristics are understood to have a major role in the final perceived color. At the present study, the effect of fluorescence in paper on color change of the printed samples was investigated. The 24 color patches from Macbeth chart were printed on an A4 white paper by using a laboratory color printer. The spectra reflectance curves of the samples were determined by a calibrated spectroradiometer under illuminant A and a combination of illuminant A and UV radiation at the visible region. CIELCH color space parameters were calculated from the measured reflectance values under standard illuminant D65/10˚. The results showed that fluorescence property of paper in many cases led to a noticeable color shift. In addition, it was shown that for achromatic samples, changes in hue were not significant but it was noticeable on lightness and chroma. Moreover, it was resulted that the selected color difference equation has a large impact to analyze acquired results.
