Fig. 1 shows a bar code label representative of the AIAG (Automotive Industry Action Group) Shipping/Parts Identification Label to be widely used in the automotive industry. The AIAG Committee has decreed that this label must be read in the so-called "picket fence" orientation. That is, the label must be placed on boxes and parts so that each bar code in the label can be read by a horizontally scanning beam. In general, this means the overall AIAG label, must be scanned by a raster scan pattern.
