Abstract
A method of using a printer system for identifying one or more different types of color objects in a document, selecting a preferred rendering option such as halftoning and/or color matching for each one of such different color object types, respectively, and then printing the document in accordance with the rendering options selected for each of such different color object types. In a printing system such as an inkjet color printer coupled through a printer driver to a host computer, a default halftoning technique and a default color-matching map are incorporated into the printer system for automatic invocation whenever a particular color object type is printed.
