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. ...

위도, 경도, 고도 등의 지리적 좌표와 같이 컬러 또한  L*a*b* 값을 사용하여, 정확한 색상 값을 지정하고 그것을 기반으로 커뮤니케이션을 할 수 있습니다. What’s the history of L*a*b*? 1940년대에, Richard Hunter박사는 3차원 공간 모델인 Lab을 개발하였습니다. 이 LAB 모델은 인식된 색상 차이를 동일한 공간영역으로 나타내기 위해 구성되었습니다. 31년후, CIE는 Hunter’s Lab의 업데이트 버전인 CIELab을 발표했습니다. CIELab을 올바르게 읽는 방법은 “see-lab” 또는 “L-star, a-star, b-star,” 이지만, 일부의 색상측정 장비나 어플리케이션은 간략화 하여 L,A,B 또는 Lab이라고 표기하기도 합니다. What does L*a*b* stand for?  어떠한 식으로 CIElab을 부르던, 더 중요한 것은 L*a...

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...
