Understanding Specular Component Included (SCI) and Specular Component Excluded (SCE) Surface conditions can influence the color and appearance of objects. A blue glossy object will appear more saturated while a similar object with irregular surface will appear duller. Human perceive colors by the light that is reflected off an object and different surface condition reflects light differently. ...

Illuminant Metamerism In White Goods            Illuminant Metamerism or light source metamerism is a phenomenon where two colors appear identical under a specific light source but different under another. Metamerism is a common challenge for appliance manufacturers and is often due to the difference in pigments, dyestuff or materials used. The exact same colorants should be used when formulating ...

Automotive Exterior Evaluation – Small and Curved Metallic Painted Parts            For automotive manufacturers, ensuring color consistency across all adjacent parts is not only a statement about their product quality, it is important to their brand as well. Qualifying a car is a challenging process and one such challenges would be measuring the color of parts with small or curved surface. When a...

Measuring Cosmetic Color Additives              Color additives or colorants play an important role in creating a vast array of cosmetic color and shade available today. Most cosmetic products are formulated using multiple color additives due to shade variation of similar color additive between batches. The use of multiple color additives allows cosmetic manufacturers and chemists to cr...

Distinctiveness Of Image vs Reflected Image Quality    Distinctiveness of Image (DOI) and Reflected Image Quality (RIQ) are parameters used for measuring the quality of a highly polished, coated or chromed surface. A DOI of 100 indicates perfect image reflection and the value decrease with orange peel effect, haze (brush marks, scratches, and dust) on a surface. Both parameters quantify the devia...

What Is Inter-Instrument Agreement? The coordination and communication of a sample or product color specification can be tedious when multiple plants or suppliers are involved. This is further escalated when different color measuring instrument models are used across these locations. This can potentially result in costly rework, waste, and rejects, hence, the use of similar color measuring instru...

How To Measure the Gloss Of Small Parts Or Curved Surfaces Gloss measurement of small parts or curved surfaces using conventional gloss meter is not possible. The aperture of these gloss meter is usually larger and small samples are not able to fully cover the aperture or there will be gaps on curved parts.   Most gloss metes are designed to measure large and flat surfaces. When used on a cu...

Probiotic Milk Beverage Color Measurement    Color plays an important role in shaping customer perception of food. Customers often use sensory characteristic to determine a product quality and safety. For probiotic milk beverage manufacturers, the ability to produce the right color consistently is not only a statement about their product quality, it is important to their brand as well. Color measu...

Identifying Metamerism With Spectrophotometer   Metamerism happens when the two objects with the same color appear identical under one light source but different under another light source. For example, the shirt and pant which appear to have similar shade of black under the retail store lighting looks dark blue and greyish black respectively under sunlight. This phenomenon is mainly caused ...

  How Does Color and Appearance Measurement Works In Industry 4.0?   Industry 4.0, the buzzword for manufacturing in the near future embrace Internet of Things (IoT) technology into manufacturing. Often termed as the 4th industrial revolution, Industry 4.0 works towards using digital technology to build things efficiently. The core of Industry 4.0 is a smart factory using information and...

Basic Color Spaces  (Part 1)            Hue, lightness, and saturation. These tree elements are the three color attributes, and can be put together to creatre the three dimensional solid shown in Figure 1 would be created. The shape of the color soild is somewhat complicated because the size of the steps for saturation are different for each hue and lightness, but the color solid helps us to ...

                  Disposable gloves are widely used in many industries such as healthcare and food for personal protection or contamination prevention. They are generally made from synthetic elastomeric material like nitrile and vinyl or natural rubber latex. Traditionally, color of disposable glove are only available in white or blue.

LEDs have created a completely new product category in general lighting. As a new technology, SSL is the light of the future with exciting opportunities but also challenges. Since the manufacturing process of LEDs requires extensive testing at the production stage and during quality assurance, SSL products have also placed more stringent demands on optical characterization. The electrical operatin...

LED Test & Measurement – a proven track record (BLOG-308_IMAGE1) LEDs cannot be manufactured with consistent optical properties as a result of the production processes involved. Brightness and color can vary substantially from component to component even in the same production batch. This is why LEDs have to be tested during production and in their final application. Comprehensive optica...

Plasticizers are additives that increase the flexibility and durability of a material. Large quantity of them are used every year to produce plastic compositions, coatings, films, and filaments for applications in many industries such as automotive, medical and consumer goods.
