This process allows one to create bar code and dot code labels that are sensitive to infrared, visible, and ultraviolet light with out the use of ink. This is accomplished by cutting out or otherwise removing select areas of media to create shapes identical to the outlines of data elements that would be created by infrared, ultraviolet, and visible ink printing systems. This includes but is not limited to the shape of bars in bar coding, the dots in dot coding, lettering, numbering, and images. The method of cutting out the shapes could be manual or with special automated tools, equipment, and machinery. This process offers distinct advantages that qualify it as an improvement over ink printing. It can be done more cheaply, has a stability that is more dependant on the media than the ink, can not wash off, and there are no problems involving insufficient ink and poor print quality.
