Abstract:
Pantograph background and foreground pairs that perform well in one printer may not perform as well in another. The main problem that occurs is the message is easily seen on the original print. By adjusting the background pattern quality, the pantograph is adjusted for optimal performance for a particular printer. The background pattern is adjusted by first adjusting the pixel density in the background pattern and second, by adding the adjusted cluster background pixel pattern.
