Opacity readings

Web26 de fev. de 2024 · Transmission vs. Reflectance Measurements. Both transmission and reflectance spectrophotometers emit all of the wavelengths of light from 360 -750 through the flash, then measure the light that is transmitted or reflected to create a quantified graph – a fingerprint – of that color. The dominant wavelengths that reflect back indicate the color. WebOpacity refers to the property of paper which obstructs the passage of light and show-through of printing. This characteristic is expressed as the percentage of visible light that does not pass through a sheet of paper. …
