Abstract:
1. Inkjet printing apparatus for radiation curable ink comprising: a support for receiving a substrate; a print head for directing radiation curable ink toward a substrate received on the support; a source of radiation for providing radiation to ink received on the substrate; a sensor for sensing the amount of radiation emitted by the source of radiation, wherein the sensor is laterally offset from the substrate when the substrate is received on the support; a controller having an input for receiving a signal from the sensor and at least one characteristic of the ink, substrate or printing productivity parameters, wherein the controller is connected to the source of radiation and varies the amount of radiation delivered by the source of radiation in accordance with the signal received from the sensor and the at least one characteristic of the ink, substrate or printing productivity parameters; and a drive mechanism for moving the source of radiation across the substrate and toward the sensor.
