Abstract
An ink jet printing apparatus for producing an image on a gelatin coated ink receiver includes, at least one ink reservoir for providing ink for printing the image; a first print head coupled to an ink receiver and at least one ink reservoir, for producing disposing ink spots on the ink receiver; a hardening fluid reservoir for providing a hardening fluid for treating the ink spots disposed on the receiver; and a second print head coupled to the ink receiver and the fluid reservoir, for depositing the fluid on the ink spots disposed on the ink receiver whereby the gelatin coating is cross-linked with the hardening fluid thus improving the image stability and durability of the image.
