Abstract:
1. A method operative to control image consistency in an image rendering system that includes an image input device operative to generate a computer readable representation of an imaged item and a plurality of marking engines operative to render printed images on print media based on the computer readable representation, the method comprising: predetermining a test image; printing a first rendered version of the test image on print media with a first marking engine of the plurality of marking engines; generating a first computer readable representation of the first rendered version of the test image with the image input device; printing a second rendered version of the test image on print media with a second marking engine of the plurality of marking engines; generating a second computer readable representation of the second rendered version of the test image with the image input device; determining image consistency information from the first computer readable representation and the second computer readable representation; and if necessary, adjusting at least one aspect of the image rendering system, in a manner predetermined to improve image consistency, based on the determined image consistency information.
