What does the Rhopoint IQ-S measure? Gloss is measured by shining a known amount of light at a surface and quantifying the reflectance A measurement proportional to the amount of light reflected from a surface. The peak gloss measured over a very narrow angle. Geometry: The correct measurement geometry should be used according to the sample finish – matt: 85°, mid gloss: 60°, high gloss: 20° Usage: It is very sensitive to surface texture and can be used to identify subtle differences in smooth surfaces. 3. Distinctness of Image (DOI) A measure of how clearly a reflected image will appear in a...

4. Reflected Image Quality (RIQ) RIQ is used to quantify effects such as orange peel and surface waviness. This new parameter gives higher resolution results compared to Distinctness of Image (DOI) measurement and better mimics human perception of surface texture, especially on high quality finishes such as automotive applications. Symptoms of poor RIQ: Orange peel, brush marks, waviness or other structures visible on the surface. Reflected images are distorted. Causes: Application problems, incorrect coating flow, coating viscosity too high/low, sag or flow of coating before curing, incorrect...

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 a 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: from highly reflective car body panels to glossy magazine covers or...

How is gloss measured? Gloss is measured by shining a known amount of light at a surface and quantifying the reflectance. 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. Low Gloss: 85° For improved resolution of low gloss a grazing angle of 85° is used to measure the surface. This angle is recommended for surfaces which measure less than 10GU when measured at 60°. Gloss is measured by shining a known...

Why measure haze? Haze can be described as near specular reflection. It is caused by a microscopic surface structure which slightly changes the direction of a reflected light causing a bloom adjacent to the specular (gloss) angle. The surface has less reflective contrast and a shallow milky effect. In the coatings industry, this microscopic surface texture is often due to poorly dispersed raw materials, incompatible raw materials or oxidisation and weathering. For polished metal surfaces, haze is often associated with polishing marks or chemical residue. Reflection haze Haze is light that has...

The instrument processes this high resolution data, selecting individual elements within the array that equate to the angular tolerences outlined in international measurement standards. In a single 20° measurement,...

Incident light Gloss and Haze component Diffused light Yellow pigment in paint film The Rhopoint IQ-S compensates for reflection from within the coating for highly reflective pigments, metallic coatings and speciality pigments, allowing the haze of any painted surface to be measured. Diffuse corrected measurement with array technology* Reflection haze is caused by micro texture on a surface which causes a small amount of light to be reflected adjacent to the gloss angle. For white surfaces, bright colours and metallics, a certain amount of diffuse light, reflected from within the material, is...

Simultaneous measurement of all parameters, date and time stamped. Statistics Displays full statistics for the readings in the current batch. Graphs Graphical reporting for quick trend analysis. View and inspect data saved on the instrument, Goniophotometric Curves Different types of surface textures produce identifiably shaped reflectance profiles. This goniophotometric data can be downloaded to PC for further analysis and comparison via the USB cable or Bluetooth. Pass / fail parameters can be defined for instant identification of nonconformances.

Applications The DOI, Haze and RSpec values measured by the Rhopoint IQ-S allow the user to quantify and control the surface textures that reduce the perceived quality of manufactured products. The meter is widely used throughout many industries to assess the reflective qualities of products, in particular automotive exteriors and interiors.
