Gloss is an aspect of the visual perception of an object. It is a property of the object surface with a glossy, metallic or matte appearance. The more direct the reflected light, the more pronounced the gloss.
The gloss effect is based on the interaction of light with the physical characteristics of the object surface. The human eye is a tool for assessing gloss differences. The subjective perception of an object's appearance depends on personal experience: paper makers believe that a smooth surface may not be the case for car manufacturers. Gloss is measured by focusing on the reflected image rather than by focusing on the surface. Vision and emotion play a decisive role in visual judgment. Again, what matters is what our eyes want to focus on. We evaluate the surface by focusing the eye on the reflected image of the light source. However, because there are no clear rules, different people have different sights and judgments, so judging the gloss with vision is not absolutely convincing. In order for a product to achieve acceptable gloss, it is necessary to define the appearance with objective, measurable criteria. We can use the professional instrument-gloss meter to judge the gloss of the product appearance. Accurate definition of appearance not only helps control product quality, but also improves quality and optimizes production processes.
When considering the psychological impact of a product on consumers, gloss is an aspect of object visual perception, as important as color. In other words, "gloss" is defined as a property that gives a surface a glossy or shiny metallic appearance. The surface gloss can be affected by many factors, such as the smoothness obtained during polishing, the number and type of coatings, or the quality of the substrate. Manufacturers pursue products with the right gloss to achieve the perfect product appearance. Examples include highly reflective body panels, glossy magazine covers or furniture. If the gloss of the same product is different, customers with poor gloss products will be regarded as product defects. We can use the gloss meter to measure the gloss of objects to help manufacturers solve this problem.
Therefore, it is important that the gloss of each product or different batches must be consistent. Gloss can also be a measure of the object surface quality. For example, a decrease in the gloss of a coating's surface may indicate a problem with its cure, leading to other failures, such as poor adhesion or lack of protection. For these reasons, from automotive, printing and furniture to food, pharmaceuticals and electronics, many manufacturing industries monitor the gloss of their products. Therefore, the gloss meter is a professional instrument necessary for these manufacturers to measure gloss.
