Abstract
Abstract A system calibrates a computer print image. A page driver receives an image having image properties, such as color scheme, image resolutions, contrast, etc., and sends it to a journal file for storage. A user interface enables selection of a property of the image. A journal file processor generates specific values based on a selected range of values for controlling the characteristics of the selected property. A rendering driver renders a modified version of the image for each generated value, and sends the modified versions to the printer. The user interface enables the selection of a preferred image from the rendered modified images. The journal file processor sends the values of the selected image to the driver settings file for storage. The user interface enables printing of the image using the values stored in the driver settings file, repetition of the above process for the same property over more specific range of values about the property value of the selected image, or repetition of the process for an entirely different property.
