Abstract
A printing system includes a media transport system configured to transport a web of print media through a printing zone at a transport speed in a transport direction proceeding from up-web to down-web. A plurality of printheads each at least spanning the print zone and each configured to eject a radiation-curable ink. At least one PIN is unit positioned between two of the printheads relative the transport direction and configured to emit radiation onto the print media to partially cure the ink emitted by a printhead that is up-web from the PIN unit. A controller controls a power level of the PIN unit so that the radiative power level of the PIN unit decreases as the transport speed increases.
