Abstract
The present invention relates to a method and product resulting from the application of distortion security images in a digitally printed color anti-copy document, printed on demand, which may be variable use laser printers or printer/copiers and/or ink-jet printers and/or digital presses at any resolution.
Claims21
A digitally printed color document at any resolution comprising:
- a first printed portion comprising non-reactive colorized area;
- and
- a second printed portion comprising reactive region of colorized shape elements, adjacent to said first printed area,
- wherein copiers and scanners reproduce the non-reactive digitally printed colorized areas differently than the reactive region of colorized shape elements.
A storage medium having stored thereon a secure digitally produced electronic art file that when executed by a machine results in a color digitally printed document having a printed surface printed by digital print equipment comprising:
- a non-reactive area, wherein said non-reactive area includes a colorized continuous tone with an assigned percentage of a specified color alone or in conjunction with colorized shape elements with an assigned percentage of a specified color, wherein said colorized shape elements are selected shapes from the group consisting of dots that are round, diamond, ellipse, square and/or cross, and said shape elements are placed randomly according to an algorithm in a stochastic process;
- and
- a second reactive area, wherein said second reactive area comprises colorized shape elements with an assigned percentage of a specified color, wherein said colorized shape elements are a selected shape from the group consisting of dots that are round, diamond, ellipse, square, cross, continuous lines, broken lines, dashes, and/or wavy lines, wherein said elements are defined in size and are placed at specific line angles,
- wherein said document is anti-copy to digital and analog copiers.
A color digitally generated electronic distortion security feature for a document comprising:
- a pattern comprising a first printed portion of non-reactive colorized area;
- and
- a second printed portion comprising reactive region of colorized shape elements, adjacent to said first printed area, wherein the areas are at a predetermined relative percentage of a specified color,
- wherein said relative percentage of a specified color of the colorized non-reactive and reactive areas are configured to the specific output device, processed by the RIP (raster image processor) or printer driver, then printed by the digital printing equipment.
