For example, if a box contained dosage instructions in black and a warning printed in red, the bar code may be printed using groups of red and black bars. Automated scanners on the packaging line would detect any packages where one of the colors was not printed due to an error on the printing press, thereby avoiding the possibility of a package being used which did not contain the important information.
