Abstract:
A method of printing a composite image composed of a postage indicia image and an adjacent nondescript image on an image receiving medium utilizing a combination of ink jet printing technology for said postage indicia image and a printing technology other than ink jet for said nondescript image, said postage indicia image and said nondescript image being printed by separate printing devices having different inks, said method comprising the steps ofA. providing a pair of printing devices, one of which incorporates ink jet technology and includes an ink jet print head having an array of ink jet nozzles, a reservoir for holding a supply of ink, and actuating means interposed between said array of nozzles and said reservoir for ejecting ink from said nozzles in a predetermined image pattern, the other of which incorporates a non-ink jet printing technology, B. providing said ink jet printing device with a machine readable waterfast non-fluorescent ink that reduces smearing and providing said non-inkjet printing device with conventional fluorescent ink compatible with non-inkjet printing devices, C. causing relative movement between said image receiving medium and said ink jet printing device and said other printing device, and D. activating said actuating means of said ink jet print head and said other printing device simultaneously during a single pass of said relative movement between said image receiving medium and said print head and said other printing device, so that ink from said ink jet printing device and from said other printing device is deposited on said image receiving medium during said single pass in a predetermined sequence of operation for said print head and said other printing device, whereby said postage indicia image is printed with said machine readable waterfast non-fluorescent ink that reduces and said nondescript image is printed with said conventional fluorescent ink compatible with non-inkjet printing devices.
