reflectionsdensitometri
Reflectionsdensitometri is a measurement technique used to quantify the optical density of a surface by assessing reflected light. It is primarily employed for analyzing inks, coatings, dyes, and printed materials, where the amount of absorbing material on a substrate reduces the amount of light reflected back to the sensor.
Principle: A stable light source illuminates the sample while a photodetector records the reflected irradiance. The
Instrumentation: Reflective densitometers typically comprise a light source, an optical path to a detector, a calibration
Applications: In the graphic arts and printing industries, reflectionsdensitometri is used to monitor ink densities, verify
Limitations: Measurements reflect surface reflectance and are influenced by substrate color, gloss, and measurement geometry. Accurate
