The fineness of printing ink can be measured using an NPIRI fineness of grind gauge. The ink is drawn along precision-ground grooves and assessed using the graduated scale to determine its fineness of grind. The Elcometer 2070 is specifically designed to measure particles in printing inks according to the National Printing Inks Research Institute (NPIRI) scale.

Printing inks contain very fine particles, so a gauge offering suitable resolution is required. The Elcometer 2070 NPIRI Fineness of Grind Gauge is specifically designed for printing inks and features two grooves with a gentle gradient and 2.5µm graduations for improved resolution.

The NPIRI scale is a measurement scale associated with the National Printing Inks Research Institute and is used when assessing the fineness of grind of printing inks. The Elcometer 2070 displays the NPIRI scale alongside a micron scale, allowing printing ink fineness to be assessed using both scales.

An NPIRI Grindometer is a fineness of grind gauge designed for assessing the fine particles found in printing inks using the NPIRI scale. The Elcometer 2070 NPIRI Fineness of Grind Gauge has two precision-ground grooves and a measurement range of 0–25µm.

Printing ink particles can be extremely fine, so greater measurement resolution is useful when assessing their fineness of grind. The Elcometer 2070 uses two grooves with a gentle gradient, providing graduations of 2.5µm / 1 NPIRI for greater resolution when testing printing inks.

Yes. The Elcometer 2070 displays the NPIRI scale alongside the micron scale. It has a measurement range of 0–25µm with graduations of 2.5µm / 1 NPIRI, allowing results to be assessed using the required scale.

ASTM D1316 is the Standard Test Method for Fineness of Grind of Printing Inks by the NPIRI Grindometer. The Elcometer 2070 NPIRI Fineness of Grind Gauge is designed for testing in accordance with ASTM D1316.
