Tout responsable d’impression de produits ou d’emballages sait que certaines couleurs, comme la teinte orange, sont tout simplement trop difficiles à reproduire en utilisant uniquement des encres CMJ. Une quatrième couleur, le noir (désigné par la lettre N), est souvent ajoutée aux applications d’impression de couleurs soustractives. Puisque la combinaison C+M+J donne en fait une couleur marron terne en raison des impuretés des encres,...

Une cabine de lumière de qualité est la meilleure façon de visualiser la réponse des couleurs dans des conditions d’éclairage réelles. Les cabines de lumière traditionnelles proposent des illuminants courants tels que la lumière du jour, la lumière incandescente et la lumière fluorescente afin de reproduire l’aspect des couleurs dans les magasins et après achat, sous les éclairages d’exté...

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...

Pour mettre en œuvre un programme de contrôle qualité efficace, vous avez besoin d’une bonne instrumentation, d’un logiciel robuste et d’utilisateurs formés. Mais même si tout est en place, attention à certains pièges courants lorsque vous utilisez un spectrophotomètre pour analyser la qualité des couleurs. Measuring plastic parts with the X-Rite Ci7800 benchtop spectrophotometer. Les cinq principaux pièg...

Whether you work with plastics, coatings or textiles, you must consistently achieve in-tolerance color or your product could be rejected before it even makes it to the shelf or showroom.     This is especially true for brands that rely on off-site suppliers and manufacturers for raw materials and parts that come together at assembly, such as the plastic dashboard, fabric seats, and coated interior panels of a car. Even if each site produces in-tolerance color, it must be monitored an...

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...

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...

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....

Vers le début des années 30, les règles de la mode exigeaient que l’on ne porte pas de blanc avant le Memorial Day, qui tombe toujours le dernier lundi de mai aux États-Unis. Cet indicateur de statut social voyait les nantis ranger leurs vêtements d’hiver et prendre leurs quartiers d’été à la plage avec leurs vêtements légers et insouciants. Bien que la règle s’applique encore assez librement, la m...

Did you know that many of the products you use every day contain optical brighteners? Optical brightening agents are chemicals that manufacturers add to products like paper, plastics, and textiles to make them appear whiter and brighter, and to lessen the natural yellowing process that happens over time. They also add these chemicals to cleaning agents to enhance the appearance of materials – primarily textiles – after cleaning. Often unacknowledged by the typical consumer, OBAs trick our eyes i...

If you work in an industry where color accuracy is important, you know that lighting plays a huge role in how you perceive color. A light booth is a crucial part of any visual evaluation program. It can help you verify whether the color of your product is acceptable, plus ensure it will remain accurate in every lighting condition after purchase. When parts are manufactured at different factories, a light booth should also be used to make sure they continue to match under any lighting condition o...

De nombreuses entreprises consacrent beaucoup de temps et d’argent à l’achat d’instruments et de logiciels de mesure de la couleur, mais oublient l’importance de l’éclairage lorsqu’elles approuvent les produits pour l’expédition. Utilisés correctement, les spectrophotomètres et les logiciels de gestion des couleurs déterminent si vos couleurs sont conformes aux tolérances, et ils permettent de maîtri...
