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...

Appearance is more than just color. It’s an all-inclusive look at everything inherent to an object, including texture, gloss, transparency, translucency, and special effects like sparkle and shimmer. When viewed from different angles or under different lighting conditions, appearance effects can change our perception of color. That's why it’s important to control both color and appearance throughout design and development.  Durable goods brands use appearance effects to captur...

With so many requests for innovative bases, transparency, and special effects, formulating color for paint, coating, and plastic applications can be a challenge. To keep up, formulation software needs to be innovative, too. We recently launched version 10 of our Color iMatch formulation software, and it is our smartest version yet. It allows you to select cost-reducing parameters, such as lowest cost or fewest colorants, and will determine the best formula for your application. It work...

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...

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...
