ASTM D1316-2020 "Standard Test Method for Fineness of Grind of Printing Inks By the NPIRI Grindometer"

This standard describes a method for determining the fineness of Printing inks using an NPIRI grinder. This method determines the timing of the end of the dispersion process by assessing the size of the largest particles in inks and verifies that inks meet the requirements of suppliers and customers. Determining the fineness of Printing inks is essential to guarantee the uniformity of inks and printing quality. Suitable for inks with a fineness range of 0 to 25 μm, this test helps to avoid particle problems during printing.
