Did you know there is more to measuring color than just the color itself? Sure, you want that beautiful shade of Chinese Porcelain blue you developed to be the exact same color your designer saw on the streets of Hong Kong. But that’s not all you can do with our instruments and software. Here are just a few applications our customers have discovered with the SpectraVision solution:
Calculation of percentage coverage
The concept is simple. When measuring multi-color or mixture material, the system calculates the % of a certain color within the total sample space.
Why is this important?
First, it can give you an objective evaluation of the overall look and feel of the material. Take heather, for example. Heather can be made with a blend of fibers or yarns of mixed colors producing flecks of an alternate color. Traditionally, visual evaluation was the only method for controlling consistency of the overall look and feel of heather. Now, with the introduction of new technology on the market, a textile producer can separate the different colors in the fabric and determine if the individual colors match the standards. In addition, the ratio of color can also be used to evaluate if the pattern is consistent across multiple lots.
Second, it can help you meet technical specifications or control the cost of material. Take, for example, roof shingles or sandstones, which contain different mixtures of sand, colored stones, or other materials used to create different coloring effects. But these raw materials come at different costs. Understanding how much of each material the sample contains can help you control cost while still ensuring overall consistency of the final product.
Separation of color for textured material – excluding shadows
When it comes to accurately assessing color for textured material such as stucco, leather, textured wallpaper, etc., a traditional spectrophotometer just doesn’t cut it. That’s because a standard instrument takes an average of the sample measurement space—including the shaded areas. This results in errors in the lightness of the samples.
However, with a hyperspectral imaging solution like the Datacolor SpectraVision, a user can easily separate different colors and exclude the shadow (peaks and valleys). The result? More accurate measurement of the intended color. With this capability, producers can ensure greater color matching and consistency from batch to batch.
Color separation with small-sized samples
Products with color variation that are very small in nature, such as small buttons, hair samples, yarn dyes or small gems, can also be a challenge for a traditional spectrophotometer. With SpectraVision and its various sample holders designed to hold very small objects in place, users can easily take the images of the sample and then separate the colors—down to a 28-micron pixel size. Now that is pretty small.
This application would also prove useful in the textile industry, where manufacturers need to ensure the color consistency across multiple components of one garment, such as the zippers, buttons, trims and snaps of a jacket, or the lace, mesh, sole and body of a sneaker.
Measurement of 3D objects
Some of the more interesting samples our customers have measured with SpectraVision involve 3D objects. The ability to measure color on the top and multiple sides of a stone at the same time helps our customer to better understand their cutting process and its impact on final product quality.
Another application of 3D measurement: Did you know that tooth color is more complex than meets the eye? There are colors on the surface of the tooth and colors within the tooth. Many factors can impact the perceived color of a tooth, so the ability to measure the color gradient across a dental implant helps our customer to better control the quality of their final product.
