Abstract

Print quality tests using off-the-shelf color electrophotographic printers revealed systematic tone fluctuations among the first several pages in print jobs after idle periods as short as 1 min, under certain environmental conditions. It can be shown that the tone values on the first few pages of a print job after 1 min of idle are statistically different from the tone values on the other pages of the same job. In the mid-tone ranges, the mean tone value difference between pages can differ by 4 ΔE76 units under low temperature and low humidity conditions. This article presents an experimental approach to characterize this type of transient tone deviation in a print job for tone consistency control and improvement. A first-order difference model is employed to approximate the transient tone deviation. The resulting model can accurately predict the transient tone deviation over pages to within 1.3 ΔE76 units, based on cross-validation.
