This standard establishes a unified set of communication rules for characteristic information between offset ink suppliers and printing enterprises. It aims to standardize the transmission process of key indicators such as ink lightfastness, transparency, drying mechanism, and solvent resistance, thereby optimizing printing production planning and ensuring that the final product meets its intended use. Its core purpose is to address communication barriers caused by inconsistent information descriptions between upstream and downstream players in the supply chain, providing a technical basis for precise ink selection and process matching. Although the standard focuses on the standardization of information exchange, in practical applications, to ensure the accuracy of the transmitted parameters, ink suppliers typically use printability testers to simulate proofing and rely on devices such as spectrophotometers and drying time testers to quantify and verify the various properties of the ink. This ensures the reliability and repeatability of the communicated data.
