Chabges ofF Print Surface Properties due to Accelerated Ageing

The optical properties of the ink-jet and electrophotographic prints, printed on the offset substrate, have been examined. The measured samples were exposed to the accelerated ageing under the temperature 80 stC and 65% relative humidity. The changes of optical properties have been examined in the visible part of the electromagnetic radiation. The degree of the print quality has been presented by comparing the measured spectral reflectance with the theoretical reflectance evaluated by Murray-Davies model.
