The Influence Of Coating Structure On Sheet-Fed Offset Ink Setting Rates, Ting Chen
Masters Theses
Much attention has been paid to the study of quickset ink setting as a complex ink-coating interaction. Offset ink setting rates are typically measured as ink splitting forces versus time and the slope of the regression line obtained from a plot of these measured values is reported, but scant attention has been paid to the deviations from that straight line. An initial slow ink setting rate is desired to minimize back-trap mottle, carryover picking and piling and enhance ink gloss; then a faster ink setting rate during sheet delivery to the pile is desired to reduce the likelihood of ink …
