Gloss

Glossmeters and their handling procedures had to be internationally specified to allow comparison of measurement values. The angle of illumination is of high influence. In order to obtain a clear differentiation over the complete measurement range from high gloss to matte, 3 different geometries, i.e. 3 different ranges, were defined:
In addition, there are industry specific applications for 45° and 75° measurement geometry.

In this case study 13 samples were visually ranked from matte to high gloss and measured with 3 specified geometries. In the steep slopes of the curves, the differences between the samples can be clearly measured, while in the flat part, the measurement geometry no longer correlates with the visual.


Gloss measurement for any application – whether you are dealing with specific applications or need a universal solution for high to matte gloss samples, BYK-Gardner offers a complete line of glossmeters:


• Reference laboratory instrument – haze-gloss
• Portable micro-gloss family


Their unique features and benefits have made them the industry standard for gloss measurement.
