Abstract
A plurality of individual marks are imprinted in the surface of an object to form a plurality of substantially linear, rectangular arrays of preselected width in the surface of the object. Each imprinted substantially linear, rectangular array is spaced a preselected distance from each adjacent imprinted, substantially linear, rectangular array to provide a space of preselected width. The preselected width substantially linear, rectangular arrays and preselected width spaces are combined in alternating fashion to provide a bar code message in the surface of the object.
Claims8
A method for imprinting a machine readable bar code message in the surface of an object comprising the steps of;
- providing an object,
- imprinting a plurality of marks by indenting the surface of said object and forming recesses therein, said plurality of marks arranged in a plurality of substantially linear, rectangular arrays in the surface of said object,
- spacing each imprinted substantially linear, rectangular array a preselected distance from each adjacent imprinted, substantially linear, rectangular array to provide a machine readable bar code message imprinted in the surface of each object, and
- positioning each of said marks so that the adjacent edges of each of said marks are in juxtaposition with each other to thereby maximize the density of said plurality of marks imprinted within each said substantially linear, rectangular array to minimize errors in reading said machine readable bar code message.
