Abstract
A system for dynamically generating a digital image comprising a security feature for a document. The system includes a processor 222 configured to receive data indicative of a security feature to be embedded in the document. The processor 222 generates a digital image having content at least partially specified by the received data. The processor 222 transmits a signal indicative of the generated digital image. The generated digital image has a foreground and a background, at least one of which includes a line screen pattern. The foreground and the background of the digital image are configured such that a scanned reproduction of an original printed version of the digital image is reproduced in an altered form relative to the original printed version.
