Abstract:
1. An ink jet printing apparatus, comprising: an image receptor of one of a belt, a drum, a web, a plate or a sheet, having a central image region substantially translucent to ultraviolet radiation, the central image region on the image receptor bounded by peripheral regions having structural rigidity and being of ultraviolet radiation-opaque materials; an image generator structured to jet an ink forming a tonerless image layer on the image receptor at an image layer region, the ink including a material curable upon exposure to ultraviolet radiation of at least a first wavelength; an ultraviolet radiation delivery source positioned to irradiate the tonerless image layer region with ultraviolet radiation of at least the first wavelength to at least partially cure ultraviolet radiation-curable material jetted thereon; and a recording medium handler structured to provide a contact locus defining a nip for a recording medium and the tonerless image layer formed on the image receptor with pressure sufficient to transfer the tonerless image layer to the recording medium; wherein the ultraviolet radiation delivery source and the image layer have interposed there between the image receptor.
