<p>A method and apparatus for dyeing a substrate 10 using an array of spray generators. In a preferred embodiment, each spray generator is comprised of a gas port 140 from which an intermittent jet of pressurized gas is directed onto the substrate to be dyed. Positioned along the path of the gas jet is a nozzle 132 from which continuously flows a liquid dye. When dyeing is desired, i.e., in response to pattern data, the gas jet is rapidly cycled on and off, thereby atomizing the dye emerging from the nozzle and establishing discrete bursts of spray which meter a controlled quantity of dye onto the substrate. When the gas jet is interrupted, the nozzle projects an continuous stream of liquid dye which does not contact the substrate and is recirculated into a through 162 <IMAGE></p> |
