Abstract
A paper document, such as a business form, is printed with a pantograph that is obtained from a pattern on a negative that is substantially incapable of construction by repeating geometric or organic shapes. A positive of the pattern is scanned to create a high resolution digital image in a computer, the high resolution image is interpolated to a low resolution digital image, the image is stored in the computer, for example as full size. Alternatively a rectangular tile that can be repeated substantially seamlessly is created and using the rectangular tile as a pattern an electronic document of desired size is created by manipulating and repeating the rectangular tile pattern. At least two different density versions of the low resolution digital image are preferably produced and stored.
