Abstract
A method of automatically optimizing the controllable parameters related to producing printed material on a hardcopy output device is provided, along with a hardcopy output device configured for implementing this method. Users require different types of printed objects to have different characteristics. Specifically, business graphics need to be sharp and vivid, photographic images should look realistic, and text must be black, crisp and clear. By extracting, analyzing and conditioning data generated during a printing stream, the various regions of text, graphics and photographic images on a sheet are distinguished, characterized, and printed. The resulting hardcopy output has a custom balancing of color which is pleasing to the human eye for each type of image printed, and which has print characteristics tailored for the specific elements on the page.
