    摘要: A method and system for printing documents with one or more embedded security features is provided. Security features are embedded in the document by co-printing first and second toner on a receiver before fixation by a fixing station. The combination of first and second toners in the image results in image elements that easily show alteration or are undetectable by visual means.
