1. A machine readable code for representing data comprising:
- at least one background frame region each of a specific shape and each of a single intensity color;
at least one marking window element each of a specific shape and each of a single intensity color other than the background frame region and placed on the background frame region;
wherein the position, shape, and color of the marking window elements with respect to the background frame region, defines information to be encoded.

Abstract
A color code system for encoding information on products and other substrates. The color code is printed by a color printer using single intensity colors in specific shapes aligned side by side successively. The code is predetermined. The code can be read by a video device and decode by a computer. The present invention allows for densely packed encoded information in a small space that can be cheaply and easily read and decoded.

6. An encoding and decoding system comprising:
-
a printing means for printing one or more color code patterns, each of a specific shaped background frame of a single intensity color marked by one or more marking window elements, each of a specific shape and single intensity color other than the background frame, and arranged in successive spaces which are disposed side by side, wherein the position, shape, and color of one or more of the marking window elements with respect to the background frame region defines information to be encoded; a reader for reading matter printed by said printing means; and decision means for deciding content of the code pattern read by the reader. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of encoding and decoding data comprising:
-
marking on a substrate at least one specifically shaped background frame region, each of a single intensity color; marking a background frame region with at least one marking window element, each of a specific shape and each of a single intensity color, other than the background frame region, wherein the position, shape, and color of the background frame regions and marking window elements with respect to each other defines the information that is encoded; reading the markings on the substrate by a reading means; and deciding content of the markings by a deciding means.
