About glossiness
What kinds of materials can be measured?
This product uses a 60
gloss meter for the optical system.
Therefore, this product can be used broadly for quality control
by checking gloss status or finished status of surfaces of
various materials such as painted surface, plastic, stone
material, tile, plating and metal material. Note that a
measurement surface needs to be flat. If it is uneven or curved,
measurements cannot be performed correctly. Also, in the
case of a transparent material, measurements may not be
performed correctly since it is affected by reflection from the
bottom surface.

About glossiness standard
The glossiness is an amount that represents the degree of
regular reflection when a light is applied to a surface. It is
determined by a ratio between the intensity of reflected light at
the measurement area and the intensity of reflected light from
the gloss standard plate. When the incident angle is 60
and
the light is completely mirror-reflected (100% reflection), the
glossiness is 1000. There is no unit.
Glossinesses vary in reflection ratio depending on the
wavelength of a light source to be used. Accordingly, there may
be no relevance in displayed glossinesses between gloss
