Abstract
Method of providing an image on a receiver, so that the image has reduced graininess. The method comprises providing a print head having a plurality of segments. A first one of the segments is capable of applying a spreading agent onto the receiver at specified locations. The spreading agent disperses (i.e., migrates) only over a predetermined area of the receiver. The remaining segments are capable of applying ink to the receiver after the spreading agent is applied to the receiver. The ink overlays the spreading agent. As the ink overlays the spreading agent, the ink is dispersed therein by action of the spreading agent. In this manner, graininess, which otherwise appears in a conventionally generated ink jet image, is reduced while sharpness of the image is maintained.
