皆様の色の品質管理の工程には、目視評価が含まれていますか？ もしそうでないなら、含めた方が良いでしょう。 標準光源装置SpectraLight QCを目視評価ワークフローの一部として使用 どの業種でも、色の評価は、測色計でサンプルを測色するだけではありません。測色計は色を許容範囲内だと表示していても、その結果は必ず人間の目に正しく見えるとは限りません。 顧客からの拒否を最小限に抑えるには、色管理プロセスに照明ブースでの視覚評価を含める必要があります。特に、同じ製品の異なるパーツを生産する場合です。なぜなら、工場内だけでなく、屋外や蛍光灯のある店舗など、世の中にどこで見られても、色の統一感が必要だからです。 本日は、皆様の品質管理の工程を、可能な限りレベルアップするために、目視評価するための１０のヒントを紹介します。 目視評価に欠かせない標準光源装置を使用 エックスライト社製の標準光源装置SpectraLight QCは、さまざまな光源の下で色を評価・比較するための制御された環境を提供します。ここでは、標準光源装置の導入によって、色評価の工程を最大限に活用するための 10 のヒント...

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...

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...

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. ...

2020年、製造業界は仕事のやり方を見直さなければなりませんでした。 世界中でコロナウィルスの影響により、試作品を確認するための移動が制限され、現物サンプルの出荷が遅れました。 多くのメーカーは、生産を継続するためにデジタル・カラーサンプルを使用する方法を模索し始めましたが、 問題はカラーサンプルが正しい見え方を再現できないことでした。 デスクトップアプリケーションPANTORAは、この問題を解消します。 PANTORAを使えば、ユーザーは分光測色値を計測またはインポートし、バーチャル・マテリアルとして保存、管理、表示、編集、レンダリングすることができます。 また、PANTORAはこれらのバーチャル・サンプルをAppearance Exchange File (AxF)フォーマットにデジタル交換し、3Dレンダリングアプリケーションで使用することができます。 現在、PANTORAのレンダリングパートナーはRGBデータのみをサポートしています。 しかし、スペクトルを組み込むための機能が実装されるまでは、PANTORAを使ってスペクトル・データをRGBデータに変換することができます。 ここで...

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...
