Abstract:
1. A marking system comprising: a first image applying component for applying a marking material to a substrate in forming an image on the substrate, the marking material comprising a radiation sensitive material; a first addressable irradiation device which receives the marked substrate from the first image applying component, the irradiation device providing an array of addressable irradiation elements for irradiating the marked substrate, at least some of the irradiation elements being selectively actuable, the irradiation device emitting radiation within a range of wavelengths to which the radiation sensitive material is sensitive; a second image applying component for applying a marking material to a substrate in forming an image on the substrate, the marking material comprising a radiation sensitive material; a second addressable irradiation device which receives the marked substrate from the second image applying component, the irradiation device providing an array of addressable irradiation elements for irradiating the marked substrate, at least some of the irradiation elements being selectively actuable, the irradiation device emitting radiation within a range of wavelengths to which the radiation sensitive material is sensitive; a secondary irradiation device which receives marked and irradiated substrates from the first and second irradiation devices; and a control system in communication with the secondary irradiation device, the control system determining an appropriate secondary irradiation treatment to reduce a variation in appearance between substrates irradiated by the first irradiation device and substrates irradiated by the second irradiation device.
