ISO 2846-3:2002 specifies the colour and transparency to be produced by a process colour ink set including extender intended for four-colour publication gravure printing when printed under specified gravure printing conditions. It also specifies the test method to ensure conformance.

ISO 2846-3:2002 does not specify pigments (or spectral reflectance) in order not to preclude developments which may enable different pigment combinations to be used advantageously while still achieving the colorimetric requirements specified in ISO 2846-3:2002.

NOTE ISO 2846-3:2002 may also apply to certain non-publication gravure applications.
