Abstract
Binary digital data is rendered on a surface, such as a sheet of paper, by printing a series of color patches on the sheet, with the 1 bits rendered as color patches of a first color and the 0 bits rendered as color patches of the second color. The color patches are arranged in a predetermined order along an axis on the surface. The second color relates to the first color by a fixed relationship in color space, whereby the absolute values of the first and second colors are immaterial to a detecting apparatus. The color patches can be intermixed with areas of a third color, the third color representing an average in color space of the first color and the second color.
