Annex A (informative) - Optical density profiles
Annex B (informative) - Bar code masters, storage

Defines the related and physical attributes of a bar code master, the quality criteria by which its conformity with this standard is assessed and contains helpful guidelines for its use. Covers all forms of bar code master, irrespective of the mode of origination of the initial image, meant for reproduction by conventional printing processes.
