ISO 2846 is a collection of standards that specify the colour and transparency of printing ink sets for four-colour printing. ISO standards work best when they are mutually supportive and ISO 2846 is fundamental for the application of other ISO standards, such as the ISO 12647 series of process control standards.

What does 2846 do?
ISO 2846 has been around since 1997 and has multiple parts outlining requirements for different analogue printing processes. The documents have now been withdrawn and replaced by the 2006 versions, reviewed in 2015 and so still current. The part that most commercial printers care about is ISO 2846-1:2006 which specifies the colour and transparency characteristics for proof and production printing using offset lithography. Each ink in a process colour ink set must comply with the standard for the inks to be fully conforming. ISO 2846 includes a method for testing under specified printing conditions and using a defined substrate.
