Does your quality control program include visual evaluation? If not, it should. Using the SpectraLight QC as part of a color evaluation workflow. No matter your industry, judging color is more than just measuring samples with a color measurement device. Just because a spectrophotometer says your color is within tolerance, doesn’t necessarily mean it will look right to the human eye. To minimize customer rejects, your color control process needs to include visual evaluation in a light boo...

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...

なぜ分光測色計の校正が必要なのか？ 分光測色計は現在、ほとんど100%デジタル化されています。実際、電球以外、アナログ部品はほとんどありません。デジタルは、アナログと比べ、安定性が高いものの、 許容誤差が非常に小さくなっています。このような厳しいスペックに収まるため、定期的に分光測色計の校正を行う必要があります。 電球の安定性 分光測色計と電球を使用し続けると、性質が変わり始めます。分光測色計の校正は、 このような電球の光生性能を補正するためです。慎重に校正を行うことで、電球の寿命が尽きるまで、何か月、あるいは、何年も安定した測定が可能になります。 タイルとレンズの清浄度 装置内には、色空間における2つの既知ポイント、すなわち定義された白と黒の設定があります。工場では、白のキャリブレーションタイルを定義するため、完全な反射率曲線が作られ、さらにブラックトラップ内の黒点を定義するため、完全な反射率曲線が作られました。白と黒の正確な位置は、キャリブレーションのため、デバイス内に設置されました。 白いタイルが少し汚れると、白い点が横軸の黒に向かって下がります。白点だけでなく、その線上にあ...

色は大事だと、よく言われています。なぜ大事なのか知っていますか。実際、生産工程において、色はとても重要な要素です。しかし、残念ながら、多くのメーカーは、色を正しく表現することが以前と比べ、はるかに難しくなったと気づいています。なぜなら、取引先のブランドは、より厳しい許容範囲を満たすことを求めています。 その理由の一つは以下のとおりです。 メタリックパッケージ、真珠光沢仕上げ、カスタムファブリック、鮮やかな新色など、色技術の進捗は顧客を魅了する一方で、生産における一貫性を持たせることがより難しくなっています。 たとえば、コンポジットデッキを例としてあげましょう。以前はグレーかブラウンの2択しかありませんでした。そして、デッキ全体に調和が取れていけば、お客様は十分満足されました。しかし、今では、深い木目模様やエキゾチックな色など、多くの選択肢があります。そのため、メーカーは2～3色ではなく、数10色を管理しなければなりません。統一感を出すために、より難しくなりました。 パッケージもそのひとつです。かつて、印刷された箱のみが並んでいたお店でも、今はホイルパウチやブリスターパック、マルチ基...

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...

In this series we’ve been discussing the many factors that impact how we see color, and what we can do to ensure the color we see is accurate. Light, retinal fatigue and background effects can influence our perception of color. Today we’ll look at the limitations of the human eye and brain, and talk about how to detect these characteristics, especially for individuals responsible for evaluating and judging color. Are YOU color deficient? Read on to find out. (Spoiler alert: There’s a test at the...

There are many things that affect our ability to see color. In some cases, it doesn’t matter if the red you see is the same shade I see. A barn is a barn, right? But for those who work in an industry where color evaluation is part of the job, it IS important… VERY important. In our color perception series, we’re discussing the many factors that affect how we see color and what colorists can do to ensure that the color they see is the color they are supposed to see. Today we’ll take a closer look...

As the temperature of light changes, so does our perception of color. As I mentioned in our last post, light plays a huge role in the way we perceive color. Today we’ll look at the science of color in manufacturing and photography; specifically how an object’s reflective and absorptive properties and viewing technology can impact the colors we perceive. To reflect or not to reflect… that is the question. The colors an object absorbs and reflects is determined by its material – is it metal, plas...

Computer-aided color formulation can bring huge benefits to your business. Out of the gate, even beginners can hit color targets faster, saving time, money and expensive colorants. Once you have established an accurate method, you can expect to match 95% of your color formula requirements within a reasonable color distance on the f...

According to autolist.com, over 80% of cars produced today are white, black, or some shade of gray. It’s not necessarily because bright and bold colors are more difficult to produce and match than their grayscale counterparts, they just take longer to get through the inspiration and car design process.  Believe it or not, producing a new auto color can take up to five years before it makes it to the showroom floor. It’s a long, tedious process for designers, paint...

There are many things that affect what we see. Optical illusions aren’t just fascinating; they teach us about how we visually perceive our surroundings. In our Color Perception Series, we shared some of the factors that affect how we see color and the impact it has on manufacturing. In honor of April Fools' Day, we’re taking a closer look at some of the ways our brain, eyes, and the environment can influence what we see. April Fool #1: Your Brain Let’s start with the power of t...

Light booths provide a controlled environment for judging color under different lighting conditions. They can help visually evaluate how different types of light will affect the perception of color, evaluate the color of raw materials before and after production, and ensure different components will remain uniform once they’re assembled.   But not all light booths are the same. With NIST traceability and ISO 17025 accreditation, X-Rite offers worldwide competence in calibration, cert...

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. ...
