Chiunque si occupi di stampare prodotti o imballaggi sa che alcuni colori, come l’arancione, sono troppo difficili da riprodurre con i soli inchiostri CMY. Un quarto colore, il nero (K, che sta per “Key”, ossia il nero nel mondo della stampa) è spesso aggiunto per le applicazioni di stampa a colori sottrattiva. Dato che C+M+Y in effetti crea un colore marrone fangoso a causa delle impurità presenti negli inchiostri C, M e Y, l’aggiunta di un autentico inchi...

Il modo migliore per visualizzare come reagirà il colore nelle condizioni di illuminazione del mondo reale è l’uso di una cabina di illuminazione di qualità. Le cabine di illuminazione tradizionali comprendono illuminanti comuni come luce diurna, incandescente e fluorescente per riprodurre l’aspetto del colore nel punto vendita e, successivamente alla vendita, nell’abitazione e all’aperto. Oggi, il maggiore utilizzo di lampade LED negli ambienti resid...

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...

Per definire un valido programma di controllo qualità sono necessari buoni strumenti, software validi e utenti esperti. Anche in presenza di tutti questi elementi, però, bisogna prestare attenzione ad alcune insidie piuttosto comuni quando si utilizza uno spettrofotometro per analizzare la qualità del colore. Measuring plastic parts with the X-Rite Ci7800 benchtop spectrophotometer. Le cinque principali insidie della misurazione del colore 1. Campioni e standard sbagl...

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...

I dispositivi di misurazione del colore servono per acquisire, comunicare e valutare il colore. Imballaggi in cartone, alimenti, detersivo, tappeti, piccoli componenti in plastica... questi dispositivi aiutano a garantire che il colore realizzato concordi con quello originariamente specificato. Sono utilizzati, dietro le quinte, praticamente in ogni settore in cui è importante il colore, per esempio materie plastiche, prodotti tessili, vernici, rivestimenti, stampa e imballaggi Gli strum...

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...

The World Series starts next week. While players and fans are gearing up for the big event, stadium groundskeepers are preparing, too. You’ve surely seen those meticulous patterns in the grass – crisscross, spiral, plaid – but do you know how the groundskeepers create them? Thanks to a phenomenon called geometric metamerism (aka gonio-appearance), the grass really is greener on the other side. Read on to learn more about this optical illusion that can trick your eyes and wreak havoc on y...

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....
