This time of year, the internet is full of Top 10 Countdowns. It’s a tradition we’ve embraced since 1940 when the Billboard published its first chart ranking the top selling recorded songs. Since then, others have jumped on the bandwagon to highlight the most popular trends of the previous year.   We’ve been publishing our top-read blogs since 2016, and we’re happy to see some educational topics like color perception, tolerancing, and spectrophotometers continue to r...

When customers are just getting started with color management, they often ask, "What is the difference between a spectrometer and a spectrophotometer?". With such a minute spelling difference, it's easy to make a quick typo and get the wrong answer for this color question. So...what's the difference? Spectrometers vs. Spectrophotometers    What is a Spectrophotometer? A spectrophotometer is a color measurement device that is used to capture and evaluate color on just about anything, in...

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...

測色は、色の重要な作業において、色の品質を指定・定量化・伝達・定形化・検証するために必要です。色の感じ方は人それぞれ異なるため、測色は目視評価より正確な結果を得られます。  色測定とは？ 色測定は、サンプルによって放射・透過・反射される光の量をとらえ、スペクトルデータとして定量化することで、光源の変化分も捉えることが出来ます。測色計（分光測色計）で行う色測定は、目視評価より正確です。なぜなら、人間の色認識は差を表すのは得意ですが、定量的に示すことは不得意です。色に関わる重要な作業には、色を識別・定量化・伝達・区別するための分光測色計の導入を強く推奨します。 色波長の測定方法 色を測定するには、分光測色計と呼ばれる測色装置でサンプルに光を当て、人間の目に見える波長範囲である380nmから780nmの範囲で透過または反射した光の量をとらえます。分光測色計は波長範囲にわたるスペクトル波長測定に基づき、計算を行い、スペクトルデータを定量化します。  測色計とは？ 測色計には、色彩計と分光測色計の２種類あります。 色彩計は人間の目と同じように色を認識し、赤・緑・青を感じる3...

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...
