Abstract
An ink jet system using a single transducer chamber is disclosed which can produce a wide variation in visual print density (gray scale) without a reduction in print resolution. Vehicle is mixed with the ink during the actual jet printing process to produce the desired gray scale. The system is also readily adapted to produce multi-color prints.
