Novo-Gloss Dualgloss glossmeters 20/60?
The Novo-Gloss Dualgloss gloss-meter is ideal for basic gloss measurement and is best suited for mid to mirror gloss surfaces (10 GU @60°) 60° is referred to as the universal measurement angle and is the most commonly specified geometry in applications such as paints, coatings, plastics, automotive interiors and general manufacturing. It can be used as a basic gloss assessment for any surface 20° is the angle selected for high gloss applications such as paints and coatings, polished metals as it gives an improved resolution for high gloss finishes. It is also more sensitive to haze effects that affect the appearance of a surface. Advanced features including onboard statistics and the ability to download readings, the 20/60° glossmeter is perfect for factory? or laboratory applications High Gloss Surfaces A limitation of the 20/60° geometry is that it has limited sensitivity to surface effects such as haze and visible textures such as orange peel. When present these effects will reduce the visual quality of high gloss surfaces but will have little or no effect on measured 60? gloss values The best solution for high gloss surfaces is a Rhopoint IQ 20/60° or Rhopoint IQ 20/60/85°, this directly measures haze and texture effects which are present in many applications
The Ultimate Gloss-meter
Why Measure Gloss?
Gloss is an aspect of the visual perception of objects that is as important as color when considering the psychological impact of products on a consumer. It has been defined as ‘The attribute of surfaces that causes them to have shiny or lustrous, metallic appearance.’The gloss of a surface can be greatly influenced by a number of factors, for example the smoothness achieved during polishing, the amount and type of coating applied or the quality of the substrate. Manufacturers design their products to have maximum appeal: highly reflective car body panels, gloss magazine covers or satin black designer furniture.
It is important therefore that gloss levels are achieved consistently on every product or across different batches of products. Gloss can also be a measure of the quality of the surface, for instance a drop in the gloss of a coated surface may indicate problems with its cure, leading to other failures such as poor adhesion or lack of protection for the coated surface. It is for these reasons that many manufacturing industries use glossmeters to monitor the gloss of their products, from cars, printing and furniture to food, pharmaceuticals and consumer electronics.
How is Gloss Measured?
Gloss is measured with glossmeters which shine a known amount of light at a surface and quantifying the reflectance. The angle of the light and the method by which the reflectance is measured are determined by surface and also aspect of the surface appearance to be measured.
Which Angle Should I Use For My Application?
ISO 2813 and ASTM D523 (the most commonly used standards) describe three measurement angles for glossmeters for measuring gloss across all surfaces. Gloss is measured in gloss units (GU) and is traceable to reference standards held at BAM (Germany), NRC (Canada) or NPL (UK). Universal Measurement Angle: 60° All gloss levels can be measured using the standard measurement angle of 60°. This is used as the reference angle with the complimentary angles of 85° and 20° often used for low and high gloss levels respectively. High Gloss: 20° The acute measurement angle of 20° gives improved resolution for high gloss surfaces. Surfaces that measure 70GU and above at the standard angle of 60° are often measured with this geometry. The 20° angle is more sensitive to haze effects that affect the appearance of a surface. To quantify haze, distinctness of image, reflected image quality and other surface texturing please consider the Rhopoint IQ.
