Print Quality

According to MIL-STD-130N:

Linear Bar Code Minimum Print Quality:

3.0/05/660, where the minimum grade is 3.0, measured with an aperture size of 0.005 inch (0.127 mm) with a light source wavelength of 660 nm in accordance with ISO/IEC 15416.

Data Matrix Symbol Minimum Print Quality:

3.0/05/650 measured with an aperture size of 0.005 inch (0.127 mm) with a light wave source wavelength of 650 nm ± 20 nm.

• Exception: ISO/IEC 15415 parameters Modulation (MOD), Symbol Contrast (SC), or both may measure a 2.0, providing the overall ISO/IEC 15415 grade would be 3.0 if the MOD and SC grades are 3.0 or higher.

More information about measuring print quality is specified in ISO/IEC 15415, where the overall grade is based on a single scan.

Print quality may be graded with a verifier, such as the Microscan LDP Compliance Verifier, found in many of the Brady DoD UID System packages.
