Color measurement is used to specify, quantify, communicate, formulate, and verify color quality for color critical work. Because everyone perceives color differently, color measurement is more precise than visual evaluation. How to Measure Color Wavelength To measure color, a color measurement device called a spectrophotometer shines light onto a sample and captures the amount of light that is transmitted or reflected in the 380 nm to 780 nm wavelength range, which is the wavelength rang...

Learn about light, reflection curves, optical brighteners, and more. Illuminants Electro magnetic radiation in the wavelength range from 380 nm to 730 nm is seen as light by our eyes. Low wavelengths show as blue light, then the spectrum continues from green to yellow, orange, and red. UV radiation is located in the range below 380 nm; the range above 730 nm is called infrared radiation. The visual impression of a colored body changes by the composition of the incoming light. ...

Are you wasting too much time and money on incorrect color? Even if you use the best color measurement tools available, your color will still fail without quality control. Quality control (QC) means verifying the color you specify is the same color you manufacture, throughout production. Setting up a QC program can help you accurately communicate color with clients and suppliers, inspect raw materials before you begin working, and verify your color is correct before you ship. Five Impor...

Did you read our blog: Are You Using The Right Tolerancing Method? If not, check it out. Today we’re taking the topic one step further to investigate how tolerances are chosen in different industries. A pass-fail tolerance is the amount of color variation that is considered commercially acceptable. In part, tolerances are driven by customer expectations. While color tolerances are very tight in the automotive, plastics, and paint & coatings worlds, they can be much less strict in other...

If accurate color is a must in your world, then you know the importance of color measurement instrumentation. Spectrophotometers are used in many industries to identify, formulate, measure and communicate color. They can compare samples and standards to identify even the smallest differences. From concept through formulation and production, spectrophotometers are an invaluable part of any color-managed workflow. But have you ever stopped to think how these devices were developed? Today we’ll tak...
