Abstract
Apparatus and method for digitally printing a finely detailed image using pulse width modulation (PWM) with improved productivity over the prior art. Many images, or portions of images, generated by printers utilizing PWM do not require that any of the pixels be exposed for the maximum time possible, but that a maximum exposure can be determined for a selected portion of the image, whether it is for a line, for a paragraph, or for a selected color, that can then be used to speed up the printing of that portion of the image. Thus, a less than full density exposure can be set as the maximum, and the scanning speed increased accordingly to shorten the overall time required for printing that portion of the image.
