Traffic coatings color difference refers to the degree of change of Coating Color under different lighting conditions. Traffic coatings are usually used in outdoor environments and are prone to color changes due to the influence of sunlight, rain and other natural environments. The change of traffic coatings Color will affect the readability and recognition of road traffic signs, so the color difference requirements of traffic coatings are very strict. Under normal circumstances, the color difference test of traffic coatings is carried out under Standard light source, such as using D65 Light source to evaluate the stability of traffic coatings Color by measuring the color difference between the sample and the standard color plate. The color difference test of traffic coatings is one of the important links to ensure road traffic safety.
In the field of traffic coatings, the application of color readers is crucial, it can help ensure the accuracy and conformity of traffic signs, road coatings, etc. Color, thereby improving traffic safety and urban aesthetics.
Application
Traffic signs: color readers are used to detect the Color of traffic signs to ensure that they meet standard requirements, so that drivers can clearly identify and understand traffic instructions.
Pavement Coatings: Color conformity of pavement coatings is critical to the safety of drivers and pedestrians. Color readers can be used to detect the Color of Pavement Coatings to ensure clarity and visibility of road markings.
Measurement
Prepare Samples - Collect samples of traffic signs or pavement coatings and ensure their surfaces are clean, free of damage and impurities.
Calibrated instrument - Before making a measurement, the color reader must be calibrated to ensure the accuracy of the measurement results. This includes the white reference standard of the calibrated instrument, as well as the zero point and sensitivity of the calibrated instrument.
Measurement Sample - Use a color reader to measure the Color of a traffic sign or road surface Coating. Aim the color reader's Detector at the sample surface and record the measurement data.
Record Data - Record the Color parameters of the sample, including luminance, red-green color difference, and yellow-blue color difference. This data will be used to compare with standard Color to evaluate the degree of color difference of the sample.
Analysis Result - Compare the measurement data with the standard Color and calculate the color difference value between the sample and the standard. According to the size of the color difference value, evaluate whether the color of the sample meets the requirements.
Adjust the production process - If the Color of the sample does not meet the requirements, the production process needs to be adjusted in time to ensure the accuracy and conformity of the traffic sign or road surface Coating Color produced in the future.
Through the above measurement procedures, color readers can effectively help monitor the Color mass of traffic coatings and ensure that they meet the standard requirements, thereby improving traffic safety and the overall aesthetics of the urban environment.
