This paper presents a method for automatically extracting information about the source of a CMYK file by analyzing the image data. Several features are analyzed. These include an estimation of the type of undercolor removal and gray component replacement used to generate the image, and measures of image saturation and luminance. Together, these features provide a reasonable indication of the device for which the image was intended. While it is difficult to provide the exact source of an arbitrary file, the intention is to identify, with some degree of confidence, a probable class of devices for which the image was prepared (e.g. offset vs. laser vs. inkjet, etc.) so that the burden on the user to make this determination is reduced. Experiments performed to classify CMYK images from xerographic vs offset sources show promising results.
