Colour measurement of RAL colours (K1/K5 colour fans)
RAL colours are standardised colours with each one assigned to an unambiguous number. They help to precisely determine colours. RAL colours are used in almost every field where surfaces are painted or coloured products are manufactured. These colour samples serve as reference values at the end of the manufacturing process during quality control, as well as for comparison purposes. For example, in this application, two shades of red, green and white of the RAL K1 and RAL K5 colour fans are distinguished.
colorSENSOR CFO sensors from Micro-Epsilon are ideally suited to this kind of precise colour comparison measurement as they reliably recognise different colours while enabling 100% quality control. Before the inspection starts, the sensor is calibrated to a 1.25 inch zenith white standard.
