The Fineness of Grind Gage is a flat steel block in the surface of which are two flat-bottomed grooves varying uniformly in depth from a maximum at one end of the block to zero near the other end. Groove depth is graduated on the block according to one or more scales used for measuring particle size.
The Hegman scale or National Standard scale may be abbreviated “NS” on the gage. The scale ranges from 0 to 8 with numbers increasing as the particle size decreases.

North Scale
A lesser-used scale, also occasionally employed in the paint industry. Like the Hegman scale, it is also inverted compared to the value in microns.

NPIRI scale:
National Printing Ink Research Institute. The scale begins with “0” at the infinite point and extends to “10” at a depth of .001 inches. While it is an arbitrary scale, it is a logical one in that these divisions are equivalent of tenths of mils.
The Fineness of Grind Gage is a flat steel block in the surface of which are two flat-bottomed grooves varying uniformly in depth from a maximum at one end of the block to zero near the other end. Groove depth is graduated on the block according to the scales used for measuring particle size. The grind gages with extra deep groove are available either with “Microns – scale” or “Mils – scale”.

The Wedge Printing Plate offers a convenient quality check for ink prior to use on the press. The ink can be evaluated for color, gloss, holdout, varnishability, drying time, rub and fade resistance.
