Grind Gages

Grind Gages - µm / Hegman, 2 paths

BYK-Grind Gages - µm-Hegman, 2 paths

Description

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.

  • 0 Hegman = 4 mil/100 micron particle size
  • 4 Hegman = 2 mil/50 micron particle size
  • 8 Hegman = 0 mil/0 micorn particle size
  • Grind blocks made of high quality, corrosion resistant stainless steel for extended use
  • Dual channel designs
  • Groove depth is graduated on the block showing microns and Hegman scales

  • 0 Hegman = 4 mil/100 micron particle size
  • 4 Hegman = 2 mil/50 micron particle size
  • 8 Hegman = 0 mil/0 micorn particle size

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.

  • Dual channel designs
  • Groove depth is graduated on the block showing µm, Hegman and North scales

Grind Gages - µm / Hegman / NPIRI for Printing Ink, 2 paths

BYK-Grind Gages - µm - Hegman - NPIRI for Printing Ink, 2 paths

Description

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.

  • 0 Hegman = 4 mil/100 micron particle size
  • 4 Hegman = 2 mil/50 micron particle size
  • 8 Hegman = 0 mil/0 micorn particle size

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.

  • Grind blocks made of high quality, corrosion resistant stainless steel for extended use
  • Dual channel designs
  • Groove depth is graduated on the block showing µm, Hegman and NPIRI scales

Grind Gages - µm or mils with extra deep grooves, 2 paths

BYK-Grind Gages - µm or mils with extra deep grooves, 2 paths

Description

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”.

 

  • Grind blocks made of high quality, corrosion resistant stainless steel for extended use
  • Dual channel designs
  • Groove depth is graduated on the block showing either microns or mils scales

Wedge Printing Plate

Description

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. 

  • Wedge printing plate made of high quality stainless steel for extended use
  • The printing gage consists of a precisely made channel of a fixed depth to control the ink film thickness.
  • The channel has a large surface area to evaluate ink properties.
  • The ink is precisely hand-drawn using a scraper.
  • The plate is easy to clean for quick turnaround.
