Appearance measurement is a way of putting numbers to characteristics of surfaces that we see. The ability to independently quantify appearance allows for products to be similar whenever and wherever the product is manufactured or coated.
Elcometer provide a comprehensive range of hand held instruments to measure most of the individual characteristics that generate the overall appearance of a material or coating.
Gloss
The ability of a surface to reflect light without scattering is known as Gloss. Gloss is measured by directing a constant power light beam at an angle to the test surface and then by monitoring the amount of reflected light. Different surfaces require different reflective angles. Elcometer Glossmeters cover the range necessary to measure almost any surface from high gloss to matt, from large to small surfaces - flat or curved.
Haze
Some materials appear to have considerable difference in gloss yet give comparable readings when measured with a glossmeter at one angle. These materials can be separated by measuring at a second angle and comparing the two readings. Haze is defined by ASTM D4039 as the difference between gloss at 60º and the gloss at 20º.
Shade
This is the measurement of darkness or lightness of a surface. Only shading is measured, irrespective of colour, and is referred to as ‘whiteness’. The test surface is illuminated at an angle of 45º and the intensity of scattered light at the perpendicular (Oº), is measured on a grey scale, where black is 0% and white is 100%.
Opacity
This is the degree to which a coating will obscure the surface to which it has been applied. Opacity is measured in a similar way to shade, however opacity, or hiding power, as defined by ISO 2814 involves measuring whiteness of a known film of test material on both a black (less than 5%) and a white (greater than 75%, less than 85%) substrate. A full range of opacity test charts are available.
Colour
The ability of a material to absorb certain wavelengths of light and reflect others. For example a black material reflects no light across the complete colour spectrum, whereas a pure white material reflects all of the light. All other colours reflect light at different points of the spectrum. Colour is quantified by the material’s Red, Green and Blue (RGB) values.

The new Rhopoint Novo-Gloss IQ Image Quality Haze Distinctness of Image DOI Goniophotometer Wavescan Meter uses patented technology to measure the complex interaction of a surface with a light. The instrument profiles complete specular reflectance and calculates gloss, peak specular reflectance, Distinctness of Image (DOI) and Reflection Haze. The Novo-Gloss IQ characterises reflective properties in a way that simulates the perception of a human observer, giving a detailed understanding of surface quality. Micro-structures on the surface of a high gloss surface can cause a reflected image to bloom and become indistinct, longer wavelength surface ripples known as orange peel can also distort this image. Conforms to ISO, ASTM, DIN & JIS.
