Abstract

A radiant dryer, in an ink jet printer, can be used effectively to dry the ink on a final printed image. Proposed is the implementation of a plurality of radiant energy sources distributed over the area to be dried. Alternatively, a single segmented radiant energy source is proposed wherein segmentation is achieved by appropriate blocking or filtering. Knowledge concerning coverage of the ink distribution provides a means to selectively control the amount of radiant energy required to dry the image. The proposed radiant sources provide an improvement that prevents scorching of non-printed areas and/or incomplete drying of areas possessing heavy ink coverage.
