Abstract: The present disclosure relates to electronic digital files with document security features to prevent duplication of documents. The method may include selecting a source image previously designed, where a specified tone is used to indicate a background area and another specified tone(s) is/are used to indicate at least one security feature(s) area. The method may also include selecting one or more corresponding tiles and/or one or more corresponding functions for (i) the background area and (ii) the at least one security feature(s) area, generating a converted electronic digital file from the source image with the desired security feature(s) and saving the converted electronic digital file in a format suited for use as a stand-alone graphic image or incorporated into other programs ready for output onto the output device.
