Para medir uma cor, um instrumento de medição de cor emite luz sobre uma amostra, captura a quantidade de luz transmitida ou refletida na faixa de comprimento de onda de 380 a 780 nm e quantifica esse valor na forma de uma medição espectral. A medição de cor é necessária para especificar, quantificar, comunicar, formular e verificar a qualidade da cor em trabalhos onde ela é um elemento essencial. Como as cores são percebidas ...

Learn more about light, reflection curves, optical brighteners, and more.     Illuminants Electro magnetic radiation in the wavelength range from 380 nm to 730 nm is seen as light by our eyes. Low wavelengths show as blue light. Then the spectrum continues from green, yellow, orange to red. UV radiation is located in the range below 380 nm; the range above 730 nm is called infrared radiation. The visual impression of a colored body changes by the composition of the incoming light. ...

2020 forced manufacturers to rethink the way they work. Around the globe, COVID put a hard stop on the travel required to approve prototypes and delayed the shipment of physical samples. Many brands started looking for ways to use digital color samples to keep production moving but struggled with the inability to replicate how a color sample would look on a prototype.   The PANTORA desktop application closes this gap. With PANTORA, users can capture or import spectral samples and store, man...

To establish a successful quality control program, you need good instrumentation, robust software, and trained users. But even with everything in place, there are some common pitfalls to watch for when using a spectrophotometer to analyze color quality. Measuring plastic parts with the X-Rite Ci7800 benchtop spectrophotometer. Top Five Color Measurement Pitfalls  1. Bad Standards and Samples Physical standards and samples don’t last forever. Careless handling and dirty devices can ...

Whether you’re producing textiles, automotive parts, or plastic pieces, color needs to remain consistent or the final product will be rejected. Unfortunately, there are many ways for color errors to creep in during manufacturing. Creating and using accurate digital color standards is one way to combat these errors. Digital color standards can be used in software to specify and communicate color, formulate colorants and raw materials, and control color quality. They give brand owners peac...

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...

O seu programa de controle de qualidade inclui avaliação visual? A iluminação desempenha um papel importante na maneira como percebemos as cores. Ele pode ajudá-lo a verificar se a cor do seu produto é aceitável e garantir a precisão em todas as condições de iluminação possíveis após a compra.     Muitos de nossos clientes consideram a avaliação visual ainda mais importante ao fazer a transição das revisões e aprovações de cores para um local diferente, como no escritório em casa o...

As cores sempre foram um fator crítico para nossos clientes. Devido à pandemia da COVID-19, muitos agora estão tentando projetar, especificar, comunicar e, finalmente, obter cores precisas em locais remotos ou com menos equipe e menos recursos. Você está com problemas para manter seu programa de cores neste momento sem precedentes?  Reunimos nossos recursos mais populares - blogs, vídeos, artigos técnicos, seminários virtuais e estudos de caso ...

Managing color throughout production is always a challenge, but advances in color technology, like the metallic, shimmer, and pearlescence effects designed to capture consumer attention, are taking the frustration to a whole new level for quality control managers. This is especially true when producing parts that must match at assembly, such as the metal panels for a home appliance or the painted side mirrors for a vehicle.  Special effects are tricky to control because our perception can c...

When it comes to the way we see color, our eyes can be deceived. This is partially caused by our humble brain, which is managing vast amount of information and processing it the best it can. It can also be related to genetics and the environment; we all see color a little differently. But above all, LIGHT has biggest impact on the colors we see.  Without getting too technical, here is an introduction to the way light affects our perception of color. RGB Color Circle The temperature of lig...
