Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 135 words
A bar code printing medium having a surface on which first and second bar codes to be read at two stages, respectively, are disposed separate from each other, the medium characterized in that the second bar code is covered with a colored transparent film whose optical average transmittivity in a visible wavelength region is 50% or above and whose optical average transmittivity in the reading wavelength region associated with bar code reader is 30% or below, with an inside surface of the colored transparent film being adhered to a surface of the medium and being strippable from of the surface of the medium, whereby the second bar code is visible by the naked human eye while not readable by the bar code reader unless the transparent film is stripped from the surface of the medium.
Claim 2
Dependent Claim 135 words
A bar code printing medium having a surface on which first and second bar codes to be read at two stages, respectively, are disposed separate from each other, the medium characterized in that the second bar code is covered with a colored transparent film whose optical average transmittivity in a visible wavelength region is 50% or above and whose optical average transmittivity in the reading wavelength region associated with bar code reader is 30% or below, with an inside surface of the colored transparent film being adhered to a surface of the medium and being strippable from of the surface of the medium, whereby the second bar code is visible by the naked human eye while not readable by the bar code reader unless the transparent film is stripped from the surface of the medium.
