GB/T 13217.4-2020
Test method for viscosity of ink

GB/T 13217.1-2020 "Test Methods for Color and Tinting Strength of Inks" is applicable to various types of ink products, specifying the inspection procedures for color and tinting strength. Color inspection is conducted using the blade-scraping method or the printability tester printing method, with visual inspection under D65 standard light sources or color difference measurement using a spectrophotometer. Tinting strength is evaluated by calculating the ratio with white ink. The testing environment is controlled at 23±2°C, clearly defining the ink sampling amount, mixing ratios, and result evaluation criteria to ensure the accuracy and consistency of inspection results.
