O tej porze roku internet jest pełen rankingów typu „10 najlepszych”. To tradycja, którą przyjmujemy od 1940 roku, kiedy Billboard opublikował swoją pierwszą listę najlepiej sprzedających się piosenek. Od tego czasu inni publikują swoje listy, aby podkreślić najpopularniejsze trendy poprzedniego roku. Publikujemy nasze najlepiej czytane blogi od 2016 roku i cieszymy się, że niektóre tematy edukacyjne, takie jak percepcja barw, tolerancja i spektrofotometry...
Kiedy klienci dopiero zaczynają korzystać z narzędzi do zarządzania barwami, często pytają: „Jaka jest różnica między spektrometrem a spektrofotometrem?” Przy tak niewielkiej różnicy w pisowni łatwo jest zrobić literówkę i uzyskać złą odpowiedź na to pytanie dotyczące barwy. Tak więc... jaka jest różnica? Spektrometry vs. Spektrofotometry Co to jest spektrofotometr? Spektrofotometr to urządzenie do pomiaru barwy, które służy do rejestro...
X-Rite acquired GretagMacbeth in 2006, making most GretagMacbeth handheld and benchtop spectrophotometers 20+ years old. If you're still using one of these legacy spectrophotometers and color consistency is important to your business, we encourage you to consider upgrading to a new, ISO-certified X-Rite device for the best experience. Here at X-Rite, we continue to research and improve our color measurement technology so our customers can meet tighter color control tolerances. Improved color mea...
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. ...
Our customers who are now working remotely need to be aware that changing a small variable – such as approving color from home under a different light source, or emailing specifications instead of sending a physical sample – can introduce color issues that risk creating a larger color problem. The first and most critical stage to color control is accurate color communication. These resources will help you get started. The Importance of Color Communication Blog | Many color...
Spectrophotometers (“spectros” for short) are color measurement devices used to capture and evaluate color. As part of a color control program, brand owners and designers use them to specify and communicate color, and manufacturers use them to monitor color accuracy throughout production. Spectrophotometers can measure just about anything, including liquids, plastics, paper, metal and fabrics, and help ensure that color remains consistent from conception to delivery. &nb...
Phone and computer screens are the window into the digital world of color, but if you are approving colors via email or text you need to be aware of the limitations. For starters, each of your devices relies on a different color model to display color. Input devices – your camera and monitor – use the additive color model to display color. They start with darkness and add red, green, and blue light to create a spectrum of colors. Printers, on the other hand, use the s...
Does your quality control program include visual evaluation? Lighting plays a huge role in how we perceive color. It can help you verify whether the color of your product is acceptable and ensure it remains accurate in every possible lighting condition after purchase. Many of our customers are finding visual evaluation to be even more important as they transition color reviews and approvals to a different location, such as in the home office or to another remote environmen...
So much goes into the way you perceive color, including light, genetics, the environment, human traits, and even fatigue. You may also be among the 1 in 255 women and 1 in 12 men who have some form of color vision deficiency. Our online color challenge is a fun way to better understand your color vision acuity. Regardless of your color vision acuity, if you are communicating, evaluating, or approving color from a new location your eyes may trick you into making diff...
