Graphic technology. Colour and transparency of printing ink sets for four-colour printing - Coldset offset lithographic printing

BS ISO 2846-2:2007 Graphic technology. Colour and transparency of printing ink sets for four-colour printing. Coldset offset lithographic printing

BS ISO 2846-2 specifies the colour and transparency to be produced by inks intended for four-colour coldset web offset printing when printed under specified conditions on a printability tester. It also describes the test method to ensure conformance.

BS ISO 2846-2 does not apply to fluorescent inks and does not specify pigments (or spectral reflectance) so as not to preclude the use of future suitable pigment combinations and still claim compliance with its colorimetric requirements.
