Abstract
A printing apparatus for printing images on a substrate. The printing apparatus is provided with a first print head connected to a selector valve which in turn is connected to a pair of reservoirs. The first reservoir holds one type of ink while the other reservoir holds a different type of ink. The selector valve has two selectable states. The first state facilitates transmitting ink from one of the reservoirs to the print head, and the second state facilitates transmitting ink from the other reservoir to the print head. The selector valve can be coupled to a controller which is computer operated. Alternatively, the controller can be manually operated.
