蛍光増白剤（Optical Brightening Agents・OBA）（Fluorescent Whitening Agents・FWAとも呼ばれる）を使って、製品をより明るく、より白く見せることができます。 蛍光増白剤を添加すると、製品は明るく見えますが、色の見え方が根本的に変わるため、一つの光源での目視だけでは、色を評価することができなくなりました。蛍光増白剤を含む素材やファブリックは、工場照明の下で、色が一貫して見えても、小売店のLEDや昼光、家庭の白熱灯等、他の照明条件の下では、同じ製品でも、大きく違って見えます。 蛍光増白剤を含む製品の評価をする場合は、蛍光増白剤がさまざまな光源の下で、色の見え方にどのように影響を与えるのかを定量化するために、紫外線の影響を測定できる分光測色計か、UV光源を含む標準光源を必要とします。 紫外線とは？ 紫外線は可視光線（肉眼で見える光）より短い波長のエネルギーで、電磁波スペクトルのごく一部に過ぎないものです。 この図は電磁波のスペクトルを説明したものです。左端のガンマ線から始まり、右へ X-線、マイクロ波、ラジオ波と進んでいきます。紫...

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.

そして、もちろん、自然です。母なる自然は、最も美しいカラーパレットを生み出すコツを知っています。

「2022/2023年秋冬の色彩は、安らぎと回復をもたらす色彩と、活力に満ちた色調を組み合わせることで、私たちが求める穏やかさや快適さと、エネルギーを高める活力を対比させています」と、Pantone Color InstituteでのエグゼクティブディレクターのLeatrice Eiseman氏は述べました。「矛盾に満ちた環境へ進む中、2022/2023年秋冬の色相は、消費者が対照的な色合いの間を流動的に移動することができ、その日の自分らしさや気持ちをのびのびと表現できるようにします」と述べています。

デザインナーはこうしたトレンドを意識して、消費者を惹きつける色合いの異なるパレットやコーディネートカラーを作成する必要があります。

例をあげましょう。あなたは来秋の製品パレットを決めるタスクを任されて、ちょうどアディロンダック地方に1週間のハイキングに出かけるところだとします。山肌を覆う美しい紅葉や紫、赤、黄色など。そして、鮮やかなマム、パンプキン、ひょうたんが、あらゆる色合いのオレンジ色で小さな町を埋め尽くしています。これらの色をすべて覚えていて、スタジオで再現することができますか？

おそらく無理ではないでしょうか。

人間は200万色以上の色を識別することができますが、色の記憶は非常に乏しいです。「1分前に見た色を再現してください」と言われても、ほとんどの人が失敗してしまいます。

しかし、ポータブル分光測色計を持っていけば、その問題が起きません。さらに、スタジオに持ち帰れば、さまざまな色調を簡単に再現することができます。小型で高性能な分光測色計があれば、デザインナーはいつもどこでも便利に色のインスピレーションを得ることができます。

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...

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...

Benchtop spectrophotometers measure in transmission and/or reflectance mode to capture and quantify color on opaque, transparent, and translucent samples. Reflectance spectrophotometers measure color by flashing light onto the surface of the sample and measuring the percentage of spectral reflectance of different wavelengths at 10 nanometer increments. This blog explains how a spectral reflectance measurement works so you can determine if it will meet your color measurement and quality control ...

What Do Spectrophotometers Measure? A spectrophotometer is an instrument that measures color by shining a beam of light and capturing the amount of light that reflects back or transmits through to quantify color.

Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a smooth surface of the same object.  Since spectrophotometers determine a color’s spectral values by shining light onto the surface and measuring the reflectance, choosing the right instrument an...

ICCカラーマネジメントとは、撮影からプルーフィング、最終出力まで、予測でき、一貫性があるワークフローを実現することです。 カラーマネジメントのワークフローを実現するために、デバイスのキャリブレーションを行い、カメラやモニター、プロジェクター、スキャナー、プリンターなど、すべてのコンポーネントに対して、ICCプロファイルを作成する必要があります。   なぜキャリブレーションとプロファイルが必要なのか？ 最高の結果を得るためには、ワークフローにおける各デバイスのキャリブレーションを行い、正確にカラーを実現できるようにする必要があります。 次に、同じカラーの認識が一致するため、ICCプロファイルを作成する必要があります。なぜかというと、同じ色でも、再現フォーミュラーがそれぞれのデバイスで大きく異なるからです。 カメラとモニターは同じRGBでも、色再現の手段が異なります。CMYKを使用するプリンターとプレス（印刷機）も同様です。ICCプロファイリングは、両者に共通認識を与え、カラーデータを共有できるようにするものです。 ICCプロファイル作成方法一覧   エックスラ...

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...

The color of liquid is one of the most difficult things to control during production. But it’s important. Would you choose a bottle of juice or cleaner that is lighter in color than the other bottles on the shelf? What about cough syrup?     Liquid is hard to measure because it can range in transparency from translucent to opaque. It’s also hard to hold, and the measurement device can’t touch it or the optics and the sample will both be contaminated.   Today&rsq...

ブランドオーナーがパッケージを目立たせるために競争する中、商業用と軟包装のコンバーターやラベルプリンターはより短い期間で、独自の基材上で正確にブランドカラーを実現できることが求められています 。 多くの場合は、インクの調合に多くの時間を増やしますが、色が合わないと、結局捨ててしまいます。また、調合済みのインクを保存しますが、再利用できるように時間をかけすぎるケースも少なくありません。 このような無駄なリサイクルに陥っていると、インキの購入時とインキの廃棄時に、2回インキ代を支払っていることになります。この無駄の経済性はどうなっているのでしょうか。 私たちの地球への影響について、考えましょう。 本日は、InkFormulation Software（インキ調合ソフトウェア IFS6）の残材管理機能が、在庫や廃棄物の削減、廃棄コストの低減、さらに、より持続可能な印刷環境を実現することを説明します。 インクの調合は手作業で行っていますか。 この場合はターゲットカラーまで、約12回の試行錯誤を行わないといけないことをご...

There are different levels of process control that are used for print. While visual comparisons can be used to provide a rudimentary judgment of a match, they can be very subjective, and thus not very accurate, or repeatable.  Using a densitometer can provide quantitative actionable feedback for the press operator. This can include measurements of solid ink density, tone value increase (also known as dot gain), Ink Trap, and other print characteristics. These are known as mechanical print c...

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...

When choosing a food product, consumers demand consistency in both taste and appearance. While a lighter batch of oranges may still produce a delicious juice blend, a pale color can jeopardize USDA approval and leave consumers questioning the quality. Unfortunately for food and beverage manufacturers, the color of food – especially drinks like fruit juice and blended cocktails – is one of the most difficult things to control during production. Here’s why. 1. Liquid is hard to...

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 ...

With so many requests for innovative bases, transparency, and special effects, formulating color for paint, coating, and plastic applications can be a challenge.

色が間違った状態で出荷してしまうと、コストがかかります。色を正しく修正するには、再調色のためラボに持ち帰るか、顧客先で着色をするためのスタッフを派遣するか、最悪の場合、すべて廃棄してやり直しということもあります。むだな時間と材料の費用に加えて、顧客の満足度も落ちます。 効率的に調色を行うための５つのステップ 塗料およびコーティングの業界では、適切なツールとプロセスにより、効率かつ正確な調色を行うことができます。 1. 正確な基準を決める まず、調合する色のターゲットを設定する必要があります。このステップでは、最も高精度のあるエックスライト Ci7x00シリーズをお勧めします。調合を開始する前に、サンプルと分光データを発注先に提出し、承認を得た方が良いでしょう。 2. 手作業で調色して時間を無駄にしないでください . 目視で調色を行う場合、指定の色を許容範囲内に調色できるまで十数回の繰り返し作業が必要になることがあります。この回数は、毎日行う調色のタスクで計算すると、あっというまに数週間の時間と数十万円の材料を無駄にしてしまいます。この問題を解決するには、エッ...

Hitting offset lithographic color targets isn’t always fast or easy. The manual process of measuring color bars and making ink key adjustments takes time and opens the door to operator error. Meanwhile, the press is running (and wasting) paper and ink. To achieve accurate and repeatable color, printers need to convert their printing operation to an efficient manufacturing process and drive efficiencies in all phases of their operation. For many, a closed-loop automated solution is the...

ベンチトップ分光測色計は、ガラス、液体、繊維など、さまざまな不透明、透明のサンプルの色を透過または反射モードで測定・定量化することができます。本記事では、透過測定と反射測定の違いを説明し、どのベンチトップ分光測色計を選ぶと良いか、ご説明します。 透過測定と反射測定 透過測定と反射測定が可能な分光測色計は、フラッシュを照射し、透過または反射された光を測定し、360～750nmの間のすべての光の波長の分光透過率または分光反射率を作成します。反射して戻ってくる主波長がその色を示します。青紫、藍、そして青は、波長が短く、400～550nm。緑はその中間で、550～600nm。黄、オレンジ、赤は最も長い波長を示します。OBAと蛍光剤含む場合は、100%以上のピークに達します。 反射測定の分光測色計は、サンプルの表面に光を照射し、10ナノメートル単位で反射率を測定することで色を測定します。完全に不透明な表面を測定する場合、反射測定の分光測色計で十分です。 一方、透過測定の分光測色計は、サンプルを通して光を投影できます。反対側にある検出器は、透過した光の波長と量をとらえ、平均透過率も数値化できま...

The two most common spectrophotometers are the 0:45 and the sphere (aka diffuse/8°). We get a lot of questions about which is the best choice. Here’s the difference in how these two devices measure color, and guidelines for when to use each. 0:45 In a “fixed geometry” or “single angle” device, the first number is the starting point of the light, and the second number is where the light ends up after the reflection off the surface of the sample. In a 0:45 ...

Using a light booth to visually judge color is a great start to a successful color evaluation program. It allows you predict how color will look under multiple light sources so there won’t be any color surprises when the light changes over the life of the product. Introducing a color measurement device to capture spectral data is the next logical step. For a really great color program, you need to use both a light booth AND a spectrophotometer. This dynamic duo offers benefits you can&rsqu...

If you work behind a paint counter, you know customers can surprise you with interesting and unique objects to color match. Many samples are relatively easy to measure, but when a customer shows up with a curved baseboard panel, a square of shag carpet, or a plush toy, things can get a little tricky. A few years ago, we learned just how challenging it was for our retail paint customers to color match unique samples. We took in a bag with textured and multi-colored items and asked the person behi...

新車、消費者向けエレクトロニクスや電化製品を購入する際、製品色は品質にも影響する重要な要素です。例えば、製品の前と後ろの色が違っていれば、品質自体も疑われることでしょう。そのような心配は、正確な測色により解決します。 今日の競合市場において、メーカーは常にスキルアップを目指し、特殊効果のある仕上げを用いて製品の差別化を行っています。一方、特殊効果のある仕上げを特徴付けたり、隣接するパーツ部品と一貫性を保つためには、測色だけでは不十分であることが認識されています。 自動車産業では新車の約70%がパール系、シラリックなどのエフェクト顔料を特殊効果の仕上げに採用しています。これらのマテリアルの特性を正確に把握するためには、単なる測色だけでは不十分です。バンパーや車体パネルなど、隣接するパーツとの一貫性も確保することが必要となります。 色彩、粒子輝度感、粒子感を特徴付ける新しい MA-T 多角度分光測色計シリーズは、特殊効果のある仕様をグローバルで設定、共有、確保します。 MA-T へのアップグレード MA-T シリーズの多角度分光測色計は、特殊効果のある色材管理の指標設定を行...

Appearance is more than simply color. It’s a comprehensive look at everything inherent to each unique material we come in contact with, including texture, gloss, transparency, and special effects. Each of these characteristics plays a part and has an effect on overall appearance and understanding in relation to a single material. Objects may have several elements that affect appearance, such as the material’s surface texture, construction, overall geometry and micro-surface. The environ...

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....

We frequently get calls from customers who can’t figure out why their measurements vary, even when they’re using maintained devices. Why would a sample read one way one day, then slightly different another? Many times the culprit is thermochromaticity, and it becomes an even bigger problem as the seasons change. Every kind of material changes color with temperature. These changes cause the material to exhibit a shift in reflected wavelengths of light, which can alter our perception....

Have you ever sent out a job that passed your inspection, only to have the customer reject it for out-of-tolerance color?

For many of us, fun in the sun can lead to a summertime tan. The science behind this sun + skin interaction is melanin, a skin pigment our body releases to block the UV rays found in sunlight. The more time we spend in the sun, the more melanin is released, and the darker (or more freckled) our skin becomes. This shift in skin tone doesn’t matter for most people, but for prosthetic wearers even a slight change can be a big deal. Here’s how Royal Preston hospital in the United Kingdom is using co...
