Handheld Colorimeter NS808 Ensure Accurate Traffic Sign Coloration
A stop sign is usually a shade of deep tomato red, whereas an orange sign placed next to a construction zone will be far brighter, and nearly fluorescent, in color. When colored correctly, these two signs look very different from one another. However, if the red colors that you use to make your signs lean too heavily toward the orange end of the color scale, drivers may mistake the sign for a caution symbol, rather than a full stop. Similarly, orange construction signs that appear too deep red in color may look like stop signs when, in fact, drivers merely need to slow down. Incorrect variations in sign color could dramatically impact how drivers perceive a traffic sign, causing confusion, and sometimes resulting in unnecessary traffic congestion or accidents.
Using modern color measurement technologies like spectrophotometers in your production process can prevent these problems. Spectrophotometers create an objective basis for color analysis that avoids the inherent subjectivity of vision-based assessment. This is because there are biological differences in human color vision that may impact how color is perceived; one person’s idea of orange may appear more red to another person. Inconsistent lighting conditions and variations in background color can also affect color perception—a dark background may make an orange sign appear more bright and fluorescent than if you viewed the same color against a light, or white, background. The level of color contrast tricks the human eye.
Additionally, the human eye innately struggles to differentiate between colors that are close together on a standard color wheel, like orange and red. Orange shades fall in a wavelength between 585 and 620 nanometers, whereas red shades fall between 630 and 740 nanometers.It can be all but impossible for the human eye to accurately detect the difference between an orange shade approaching 620 nanometers compared to a red shade in the 630 nanometer range. Using a spectrophotometer, you can measure obtain accurate numerical coordinates for each color to determine whether the color of your sign meets your color standard. In other words, you can guarantee that your orange signs will be true oranges, and your red signs will be true reds.
NS808 precise traffic road sign Handheld Colorimeter is a dedicated instrument for the color measurements of traffic road signs. NS808 can be easily used to measure the brightness factor of reflecting film and chromaticity coordinates of all kinds of traffic signs. Its system has the built-in GB2893 safety color module and all the standard color modules of GB/T18833 road traffic reflecting film. So, users can choose from them freely according to application. And users can also conveniently customize polygon tolerance they want.
In the relevant standards such as "GB 2893 Security Color" and "GB/T 18833 Road Traffic Reflective Film", a color area (multiple chromaticity coordinate points) and brightness factor requirements are usually given, in D65/A light source and 45/0. Under the geometric condition, it is determined whether the sample falls within the corresponding color region, thereby determining whether the sample satisfies the standard chromaticity requirement. Since the color area is a polygon, as shown in the following figure, the judgment cannot be completed using a normal spectrophotometer. The NS808 spectrophotomeer with the traffic signpost measurement module of the SQCT software can easily solve this problem.
