Color plays a major role in our food choices. Many foods like Swiss cheese, strawberries, broccoli, and mashed potatoes always look the same. We know what to expect when we take our first bite. But what if your mashed potatoes were green? Would they taste different? Would you even try them? Why Color Analysis is Important for the Food Industry   There has been a lot of research about the role color plays in how we perceive and even taste food. These studies show that our judgment of f...

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...

Black Friday. Not only is it the much anticipated start to holiday shopping, it’s also a day manufacturers have been preparing for all year long. Whether mass-producing holiday cards, candy canes, plastic toys, or festive clothing, accurate color is a must. Manufacturers can’t ship two of the same toy if they won’t match on the showroom floor, and holiday sweaters that are a shade off will end up at a discount store instead of a fashion boutique. Perfection is especially import...

No matter the industry, our customers are all working toward the same goal: Achieve accurate color and keep production moving. Even in the best conditions, color data can be a challenge to capture and share. COVID-19-related travel bans and social distancing guidelines are making it harder than ever.    Today we’ll share three easy ways to remotely share color data so you can achieve your color goals without shipping physical samples or making onsite visits. The Benefits of Digit...

Inter-instrument agreement is a very important consideration when selecting color measurement devices for your workflow. Unfortunately, it’s such a technical topic that it leads to a lot of confusion about what it means and why it’s important. The Ci7860 sphere benchtop spectrophotomter is has an inter-instrument agreement specification of 0.06 average Delta E*, enabling brands to create the most precise master color standards. Today we’re making it as simple as possibl...

There’s been a lot of research around the role color plays in how we expect food to taste. The fact is, we judge flavor by the color of the food or drink, even before the first taste. We expect red foods to taste sweet like strawberries or cherries. White should taste like vanilla, and green is probably limey and tart or minty. Color cues can even determine whether we take that first bite. Most of us won’t even consider trying a food like mashed potatoes or pumpkin pie if it is ...

Your customer rejected your latest shipment due to color.  You checked the color before you sent it and it passed tolerance…  You did everything the same way last time and it passed tolerance…  So why did it get rejected now? We get this question from our customers all the time.  The Dreaded “Error Stack” Color rejections create waste and increase production costs. Unfortunately, there are a lot of variables that contribute to the color you produce,...

Color is our perception of reflected light across the visible spectrum. When light hits an object, it absorbs some rays and reflect others. The color of light that reflects back into our eyes is the color we perceive. The more light an object absorbs, the darker it appears. With black, very little light is reflected. Pure black in the presence of light wasn’t achieved until 2014 when Surrey NanoSystems announced the invention of Vantablack. This high-tech artificial substance absorbs 99....

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...

It’s the most wonderful time of the year! A time to reminisce… to celebrate our successes, and to explore areas that may need a little more attention in 2017. If color accuracy is on your list of things to improve, this article is for you. We’ve compiled a list of the blogs our readers found most helpful and interesting in 2016, so you can start working toward your goal of more accurate color in the New Year. Did your favorite blog make the list? Top 10 X-Rite Blogs of 2016 ...
