Why measure gloss?
Gloss is an aspect of the visual perception of objects that is as important as colour 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 quality of a 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 monitor the gloss of their products, from cars, printing and furniture to food, pharmaceuticals and consumer electronics.
