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.

Method for adjusting quality of a pantograph background pattern

The invention relates to a method for devising a pantograph. The method includes the steps of defining a message to be displayed on the pantograph, forming a background pixel format and a foreground pixel cluster pattern. The foreground cluster pattern is devised from the background pixel formation. Adjacent pixels in the background pattern are combined to form pixel clusters. The foreground pattern of pixel clusters is used to fill the characters of a pantograph message.
