Technical printing specification

The bars must be printed evenly in matt black printing ink with good edge definition.

The code must be printed on a light, matt surface.

The surface can be white, light blue, light yellow or light green.

Greater than 0.7 for a wavelength range between 620 and 900 nm (PCS: print contrast signal; dimensionless value according to DIN 66 236).

Light, matt paper produces the necessary contrast at the very least with a faultless black code printout.

The opacity of the label material for the address with integrated barcode must be at least 0.75 percent (DIN 53 146, ISO 1831).

This value can be lower if the surface of the consignment is white and carries no design or structures.

At least 80g/m²
