Abstract
Print media drying time need not be set to an artificially high 'worst case' drying time. Instead a reliable drying time is estimated based upon factors, such as temperature, humidity, media type, print quality and ink drop volume. When the estimated drying time is undesirably slow, the estimated and actual drying time is reduced by altering the ink composition of the image to be printed. One technique is to over-print or under-print with composite black rather than a true pigment black. Another technique is to deplete the black ink used throughout the image.
