Abstract
A desired image based on digital data is printed on a substrate. A subset of the digital data relating to a portion of the desired image is identified, wherein pixels associated with the digital data are of a predetermined spatial relationship with pixels intended to be of a different color as the pixels associated with the digital data. The subset of digital data is caused to activate a printhead adapted to emit ink of a first type. Data not of the subset of digital data is caused to activate a printhead adapted to emit ink of a second type, the ink of the first type being adapted to dry at a faster rate than the ink of the second type.
