Abstract
A method for encoding a machine-readable scale in which a BP code is formed from a P code with length k and whose half-bits and whole bits are alternately provided with light and dark coloring. The method comprises the steps of forming an additional coding by means of a half-bit-by-half-bit comparison of the colors of the half-bit of the BP code of length k with the colors of the bits of a P code of length k+1, and further including the steps of assigning a light or dark coloring to the bits corresponding to their significance, and placing an additional bar with a complementary color of the respective half-bit of the BP code of length k in the center of the respective half-bit alternatively, depending on the agreement or disagreement of colors.
