Markings should always be restricted to the necessary information.
They should be applied without a border, and must be easily legible and permanent.
They must be able to withstand the rigors of transportation.
Black should be used if possible.
It must, however be ensured that the markings contrast with the color of the package.
Where adhesive labels are used, the standard recommends black printed on a white background.
The colors not permitted by the DIN standard are those that are reserved for hazardous goods, for example, orange and bright red.
If goods are relabeled, both the pictorial marks and the lettering of the old markings should be made illegible. This is intended to eliminate all risk of errors and misdirection.
The specifications in the shipping documents must match the specifications on the packages themselves
Those who are responsible for the packing and labeling of goods must be familiar with the various standards, or have them available for reference, and must act in accordance with them.
For those who "only" deal with the transportation of the packages, it is important that they are able to read and interpret the markings on the packages and not that they should be able to attach or modify these markings.
