Gloss means the shine which appears on the surface of a laminated or glossy papers or thermoplastic films when a specific amount of light is provided on the surface of the material that creates the reflectance. The best method by which the angle of reflectance and angle of illumination can be measured is the gloss testing technique. The Gloss property of the material can be measured easily with the help of high quality of gloss meter. The gloss meters provides the light on the surface of the material from a determined angle to measure the gloss of the surface of the material and to measure the angle of reflection. The gloss of any kind of material is dependent on the type of the surface of the material that creates the gloss.
The concentration of the gloss is totally dependent on the angle of illumination and on the type of the material like in non-metallic surfaces like coatings and plastics, the amount of reflection along with the gloss enhances with the rise in the angle of illumination and rest of light get penetrated from the surface of the material and either scattered or absorbed according to the color.
Apart from this, metal products offer a high amount of reflection and less angle dependency as compared to non-metallic materials. The gloss measurement in both types of materials is calculated on the basis of the reflected light that reflects directly from the surface of the material as different color produces different refractive index and not on the basis of the incident light. The best possible gloss measurement value of the glossy papers is 100 gloss units. Presto offers the best quality of the glossy paper testing instrument. Visit Gloss Meter to get more information.
