About This Item
ASTM D1316 is the Standard Test Method for Fineness of Grind of Printing Inks By the NPIRI Grindometer. It is used to assess how finely a printing ink has been dispersed, which is an important factor in print quality, appearance, and process performance. By providing a standardized way to evaluate grind fineness, this ASTM standard supports more consistent testing, comparison, and quality control across ink development and production workflows.
Overview of ASTM D1316
ASTM D1316 focuses on a practical test method for measuring the fineness of grind in printing inks using the NPIRI Grindometer. The standard gives manufacturers, laboratories, and quality teams a common reference for evaluating how well ink particles or agglomerates have been broken down during processing. In use, it helps create more reliable data for product evaluation and helps align testing practices within technical and procurement requirements.
Common use cases of ASTM D1316
This standard is commonly used in printing ink development, incoming material checks, and routine quality control where grind consistency matters. It may support comparisons between batches, process adjustments, and final product verification before release. ASTM D1316 is especially relevant when a workflow depends on controlled dispersion and repeatable evaluation of ink smoothness or particle breakdown using the NPIRI Grindometer.
Benefits of using ASTM D1316
Using ASTM D1316 can improve consistency in how fineness of grind is measured and reported. That consistency is valuable for compliance-focused testing, supplier communication, and internal quality control. It can also help reduce uncertainty when evaluating product performance or troubleshooting dispersion-related issues. For organizations working with printing inks, the standard supports more dependable results and a clearer basis for technical decisions.
