ABSTRACT:
An apparatus (10) and method for reading bar codes (12) on a moving web (14) has a LED light source (16) that transmits a beam of light (18o) through the advancing web (14). A scanner (20) is arranged on a side of the web (14) opposite the light source (16) for detecting the characteristic light intensity levels corresponding to various optical densities of the web (14). Output signals from the scanner (20) are processed and manipulated for adjusting the light intensity levels of the light source (16) to within predetermined limits.
