Abstract

Described is a system of preprinting all of the colors used in a code on a prepared label or other media, and then covering the unused colors in any particular code segment with an overstrike character from an impact printer which utilizes ordinary ribbons. In Fig. 1, a number of separate colors are preprinted on the media and the code is produced by covering the unused colors with a particular pattern produced by the print element. The remaining colors define the code. In the illustration, row 5 (color 5), might be defined as a clock track and the remaining colors as the data carrying tracks. This is one of a variety of codes which might be utilized. It should be noted that the type element is in effect a negative image of the code to be reproduced. In Fig.

Multicolor Easily Printable Bar Code

Described is a system of preprinting all of the colors used in a code on a prepared label or other media, and then covering the unused colors in any particular code segment with an overstrike character from an impact printer which utilizes ordinary ribbons. In Fig. 1, a number of separate colors are preprinted on the media and the code is produced by covering the unused colors with a particular pattern produced by the print element. The remaining colors define the code. In the illustration, row 5 (color 5), might be defined as a clock track and the remaining colors as the data carrying tracks. This is one of a variety of codes which might be utilized. It should be noted that the type element is in effect a negative image of the code to be reproduced. In Fig. 2, a slightly different version is illustrated in which a single color is used and the type element overprints a bar code thereover. The type element imprints a negative image of the code and the preprinted color carries the information. The advantages of this technique is that the code may be read with fluorescent or other special devices. However, it may be produced with ordinary typewriter ribbons.

While the techniques illustrated in Figs. 1 and 2 would normally utilize impact printers, other methods may also be used for producing preprinted labels on packages and cans. Labeling equipment used by large food processors is not ordinarily loaded with special inks; therefor...
