BS ISO 2846-5:2005 Graphic technology. Colour and transparency of printing ink sets for four-colour printing. Flexographic printing
BS ISO 2846-5 specifies the colour and transparency to be produced by each ink in a process colour ink set (including extender) intended for four-colour flexographic printing, when printed under specified flexographic printing conditions. It also describes the conformance test method.
BS ISO 2846-5 does not specify pigments (or spectral reflectance), in order not to preclude developments that may enable different pigment combinations to be used advantageously, while still achieving the colorimetric requirements specified in BS ISO 2846-5.
