This standard provides a unified and standardized method for the color and tinting strength testing of ink products, applicable to various ink-related testing scenarios. It covers color assessment under different conditions such as surface color, undertone, and ink color, as well as the determination of relative tinting strength. The method includes both visual evaluation and instrumental analysis techniques such as color difference testing. The testing process requires equipment such as printability testers, spectrophotometers, colorimeters, wire-wound rods, and manual spreaders. Through standardized procedures for sampling, ink adjustment, and coating, the method ensures accurate and reliable results. It serves as an important basis for quality control in ink production, product acceptance, and application performance evaluation, providing a unified standard for quality management in the industry.
