5 Material Challenges You Can Finally Measure Accurately with the CiF3200 For years, color teams across industries have faced the same frustrating truth: many modern materials are simply too small, too decorated, too textured, or too complex for traditional spectrophotometers to measure reliably. When your components don’t fully cover the aperture, or include multiple colors, intricate patterns, or uneven surfaces, your options shrink quickly. Many organizations fall back on visual assess...

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...

Why Optically Brightened Whites Are So Difficult to Manage Optically brightened whites are everywhere in textiles, and they are also one of the most misunderstood areas of color measurement and quality control. Optical brightening agents (OBAs) are added to fabrics to increase perceived whiteness by absorbing ultraviolet (UV) light and re emitting it in the blue region of the visible spectrum. While this effect can make whites appear cleaner and brighter to the human eye, it also introduces sig...

Navigating Volatility and Embracing Innovation The textile industry stands at a crossroad, shaped by economic uncertainty, shifting consumer priorities, and rapid technological change. According to the McKinsey State of Fashion 2025 report, brands are rethinking operations to build resilience and efficiency amid tight margins and evolving global supply chains. Sustainability, digital transformation, and value-driven shopping are now central to industry strategy. Key Trends Shaping the Textile I...

In the textile industry, delivering consistent color and appearance is essential for brand reputation and customer satisfaction. As digital transformation accelerates, brands and suppliers rely on standardized file formats to communicate color and appearance data accurately across global supply chains. Three formats—CxF, AxF, and QTX—are at the heart of this process. What Are CxF, AxF, and QTX? CxF (Color Exchange Format): CxF, developed by X-Rite and standardized as ISO 17972, is ...

色の測定器には様々な名称があります。 製品の色を安定させたいと考え始めると、最初の壁は用語の混乱です。色を数値化するための総称として「色度計」や「測色計」という表現を使います。 「色度計」や「測色計」などは、用途を表した言葉に見えますが、用途を表す言葉としては不十分です。色を数値化するためには、何をどうやって測るかが重要になります。 まず、何を測るかを考えて見ましょう。 色のついているものを大別すると、色のついた光と、色のついた光を反射している物体になります。 実は「何を測るのか」で世界が二分されます。 LEDやディスプレイのように自ら発光する光の色を測ることを「光源色測定」と呼びます。物体の表面からの反射や、物体から透過して見える色を測ることを 「物体色測定」と呼びます。それぞれの業界に必要とされる内容に合わせて、計測機器の形や表示も異なってきます。 前者...

The Challenge of Printing Whites The PANTONE Color of the Year 2026, Cloud Dancer, is more than just a trend, it’s a technical challenge for packaging converters. While white may seem simple, its appearance is impacted by substrate color, ink formulation, and the presence of optical brightening agents (OBAs). For converters, the goal is to deliver consistent, accurate whites across every run, between every plant, and throughout every region. Why Whites Are Complex in Packaging Whites are ...

Advancing Surface Texture Measurement for Accurate 3D Visualization In today’s digital design landscape, color and surface texture are inseparable when it comes to accurately visualizing materials. Whether you’re working with textiles, plastics, coatings, or automotive finishes, the way a surface interacts with light—its texture, gloss, and reflectivity—can dramatically alter perceived color and appearance. Why Surface Texture Matters Historically, color has been the pri...

The Pantone Color of the Year 2026, PANTONE 11-4201 Cloud Dancer, is described as an airy, billowy white that opens space for creativity, quiet reflection, and calm. A white that is both warm and cool, its serene presence symbolizes the need for clarity in a noisy world. And as soon as the choice was announced last week, an old debate resurfaced: Is white even a color? White is often thought of as the “absence” of color. But color science says otherwise. To understand this critical c...

Windows 10 Support Has Ended: What You Need to Know Windows 10 End of Support: What It Means for Your Business Microsoft officially ended support for Windows 10 on October 14, 2025. This means no more security updates, patches, or technical support—leaving systems running Windows 10 increasingly vulnerable to security threats and compliance risks. If your business relies on legacy software or hardware, now is the critical moment to plan your upgrade path and ensure your operations remain ...

In today’s global supply chain, brand suppliers are under constant pressure to deliver products that meet strict color standards, regardless of where or how they are produced. The key to achieving this consistency lies in the performance of benchtop spectrophotometers—specifically, their inter-instrument agreement and repeatability. What Is Inter-Instrument Agreement? Inter-instrument agreement refers to how closely two spectrophotometers of the same make and model can replicate a c...

5 Steps to Digitize Your Press Room and Defend Your Margins Margins in print are under pressure. Rising substrate costs, labor shortages, and energy volatility are squeezing profitability. At the same time, compliance audits—ISO, G7, internal reviews—are becoming more frequent and more demanding. Digitizing your press room isn’t just about passing audits. It’s about building a lean, smart operation that protects your bottom line. Here are five steps to get there: Step 1...

Sustainability in Manufacturing Is No Longer Optional From brand mandates to government regulations, sustainability is now a core requirement in print and packaging. But for many print teams, the path to greener operations feels like a trade-off: reduce waste or maintain quality—not both. The good news? You don’t have to choose. The Hidden Waste in Traditional Workflows Manual color control and fragmented workflows create more waste than you think: Reprints due to color mi...

For print and packaging, color accuracy isn’t optional—it’s essential. Yet many teams still rely on manual color control methods that introduce variability, slow down production, and quietly erode margins. If your workflow feels more reactive than repeatable, it may be time to modernize. Here are the 10 signs to watch for: Your color targets live in email threads Operators waste time searching or guessing—costing setup time and risking errors. Operators rely...

The Hidden Cost of Color Inconsistency on Packaging Color inconsistency in print and packaging isn’t just a visual issue—it’s a margin killer. Decentralized workflows, manual setups, and tribal knowledge create inefficiencies that quietly erode profitability. From wasted substrate to delayed approvals, the hidden costs add up fast. The Operational Fallout of Color Inconsistency Longer setup times as teams hunt for historical data Inconsistent output across p...

はじめに 色温度（いろおんど）は、光の色合いを表す物理的な指標であり、私たちの生活や産業活動に深く関わっています。印刷、テキスタイル、塗料、自動車、プラスチック、食品パッケージなど、色が重要な意味を持つ分野では、色温度の理解が欠かせません。 特に、色を正確に評価・管理する業務に携わる方にとって、色温度は品質やブランドイメージの維持に直結する要素です。本記事では、初心者の方にも分かりやすく、色温度の基本概念から産業における活用事例、測定方法、よくある誤解までを解説します。 1. 色温度とは何か 色温度は、黒体放射（こくたいほうしゃ）の概念に基づく指標です。黒体とは、すべての波長の光を完全に吸収し、かつ温度に応じて光を放射する理想的な物体のことです。加熱したときの色を、xy色度図上にプロットすると、下図のようになり、黒体の軌跡と呼びます。温度によって光の色が変化します。 例えば、約1,000Kでは暗い...

1. 表色系とは？ 表色系（ひょうしょくけい）とは、色を数値的に表現する方法や基準のことです。私たちは普段、色を「赤」「青」「緑」と言葉で認識しますが、機械やコンピューターは色を数値で扱います。そこで、どのように数値化するかを決めたのが 表色系 です。 具体的には、色を表すために「明るさ（輝度や反射率）」や「色味（色相、彩度）」などを数値化し、色を座標上にマッピングします。 これにより、異なる機器や環境間でも「同じ色」を再現・比較しやすくなります。 2. 表色系と色空間とは？ 初心者にとって「表色系」と「色空間」は似たように聞こえますが、実は意味が少し異なります。両者の違いと関係を理解することで、色管理の基礎知識がより明確になります。 表色系（Color System）とは？ 表色系は、色を数値で表現するための方法や原理のことを指します。つまり、色をどのよ...

はじめに 私たちが日常生活で「色」として認識しているものは、実は光の波長によるものです。その中でも、人間の目が感知できる範囲の光を可視光スペクトル（かしこうスペクトル）と呼びます。 この概念は印刷、デザイン、自動車塗装、産業用塗料など、幅広い分野で色を正しく扱うための基礎知識となります。この記事では、初めて可視光スペクトルを学ぶ方でも理解しやすいように、仕組みから応用まで解説します。 1. 可視光スペクトルの基本 光とは何か？ 光は電磁波の一種で、波長（はちょう）によって性質が異なります。電磁波には、ガンマ線、X線、紫外線、可視光線、赤外線、マイクロ波、電波などがあります。その中で、**380〜780ナノメートル（nm）**の波長を持つ電磁波が人間の目で見える光、つまり可視光線です。 可視光とは何か 可視光（かしこう）とは、人間の目で知覚できる電磁波の一種で、波長...
