The uses for gloss to appearances
The general public are similar to crows in that they like shiny new products when they make a purchase at a shop, a generalisation, but the public are affected by the appearance of objects. This is why it is important that the products are presented in their best light and most attractive manner. Measuring the level of gloss of the product, as well as the packaging that it is presented in, is central to it being appealing to a potential customer and them purchasing it.The instrument used to measure gloss is a gloss meters. This is a small device which shines a known amount of light on to the surface at a specified angle; the angle and intensity of light which is reflected determines the gloss level which is measured in Gloss Units (GU).
Angles used in gloss measurement
The standard angle of measurement is 60°, but this can be adjusted depending on the GU level. For a high-gloss finish, a 20° angle is used, whilst an 85° angle is used for matt finishes. The adapted angles give a more accurate GU level for gloss finishes on the extremities of the gloss spectrum; high gloss and matt. Gloss meters are not standard pieces of equipment for the general public; they are used by professionals in a range of industries. They are mainly used to agree on a level of gloss of a surface and set the appropriate machinery to create products at this standard and also for quality control purposes, to ensure that all of the different batches of the same product are being finished to the same high standard.
Vast uses throughout industries
There are a range of industries that rely on meters as an indicator of the shine and lustre of their products. This includes printing companies, paper manufacturers, paint manufacturers and the automotive industry amongst many others. All of these industries rely on the finished product being perfect and appealing to the customer and using a meter to ensure quality and consistency guarantees this. Overall then, measuring gloss is an important factor in many manufacturing procedures and for many products. There are a number of different gloss meters on the market which differ in performance and functionality. The most basic instruments offer only a 60° gloss reading, whilst more advanced equipment offers readings at different angles, as well as determining any haze or orange peel that may be affecting the finish of the product.
