Microlabelling system and method of making thin labels

Abstract

A method is disclosed for providing labelling of small items through the use of microlabels having colored bar codes with the microlabel being on the order of 1 mm.times.1 mm in overall size. In one embodiment, the label consists of a number of colored lines or bars similar to a black/white bar code, with each bar having a distinct color or hue, the width of the bars being in the 5-120 micron range in terms of width, the bars being either contiguous or separated by a thin bar of distinct color. One method of making ultra thin labels includes cutting or skiving an edge of a layered sheet, with different layers carrying different colors, and with the cut layers having a thickness on the order of 0.1 mm.
