Nonclogging Ink Jet Printer

The figure shows a printing scheme specifically adapted for use with ink-jet printing technology. By use of the present scheme the normal problems of clogging of the ink-jet nozzle with conventional inks is avoided.

The disclosed system utilizes an ink-jet nozzle 10 which projects a stream of particles 12, wherein the stream comprises water, alcohol or other liquids either alone or in combination. This type of material is not subject to clogging and also eliminates nozzle cleaning problems. Also, due to the viscosity of the material, much smaller droplets with attendant higher resolution are possible. The liquid droplet is deposited as shown in the figure on a belt or substrate 14. The substrate is coated with a dye soluble in the liquid media. A transfer operation then occurs in the region 16 through utilization of the two transfer rollers onto a final document 18. The actual transfer medium 18 could be a single sheet of material which is discarded after use, or it may be recycled, as shown, by utilizing a carrier belt and recoating it with dye at an appropriate station 20. Subsequent to the recoating the document may be passed by a heater 22 to complete the process.
