5 Color Evaluation Pitfalls to Avoid

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 once assembled.

What does it mean to measure color “Inline?”

X-Rite’s inline color measurement solutions help industries manage color as the product is being made. Inline systems monitor products as they are produced and alert operators as soon as color begins to move out-of-spec so corrections can be made before the product is wasted.

The TeleFlash445 spectrophotometer mounted on a traversing beam is automatically measuring the left, middle and right side of this sheet during production.

Each X-Rite inline color measurement system uses a non-contact spectrophotometer and ESWin software. Depending on the application and needs, a system may include a moving frame or robotic arm to position the spectro. Although they work as standalone units, X-Rite’s inline solutions can communicate with process control systems to provide color measurement data, or dye pump controls for real time Closed Loop Color Corrections. A system may also receive signals about events such as reel/sheet changes, machine stops or meter counts. Networked data allows you to share color standards and measurements among systems and at different locations.

Today we’ll look at how industries such as paper, textiles, plastics, glass and automotive are using X-Rite’s inline measurement solutions.

Modern Color Measurement Instrumentation

Color measurement devices have been around since the 1940s, but they’ve come a long way since then.

Duboscq Colorimeter

Built by Jules Duboscq in France in 1870, the Duboscq colorimeter was one of the first color measurement devices.

The earliest instruments were colorimeters, which used red, green and blue filters to simulate the tristimulus response of the human eye. Back in the ‘40s, they were pretty expensive so few people had access to them. Even more expensive were spectrophotometers, which measure color by sampling light at very narrow intervals across the visible spectrum.

Modern technology has paved the path for specialty devices for every kind of industry, and lower prices make color measurement devices accessible to everyone, from hobby photographers to car manufacturers.

Today we’ll look at the difference between colorimetry and spectrophotometry and the geometries that define each.

The Importance of Calibration

Why calibrate?

For the most part, today’s color measurement instruments are 100% digital. In fact, there are very few analog components inside, except for the light bulbs. Although they’re more stable than their analog predecessors, their tolerances are much narrower, and they need regular calibration to stay within these tight specs.

Using Rigs & Jigs to Measure Sample Color

Spectrophotometers are excellent tools for measuring samples versus standards to compare color differences, but what do you do if you have an irregular sample that isn’t flat or uniform in size and shape?

Achieving color accuracy can be a challenge for irregularly shaped products like liquids, plastics, cans and powders. X-Rite offers specially designed accessories for many of our instruments to help measure these hard-to-hold samples. We call them “rigs and jigs,” and they enable handheld and benchtop spectrophotometers to measure many of those odd shaped and hard-to-hold samples.

Today we’ll look at how X-Rite helps many customers, including the Algida Ice Cream Company, effectively measure their non-standard products.

Getting The Best Results With PANTONE® Colors

Whether you’re printing on press or replicating a brand’s colors on the web, PANTONE’s Color Systems are the gold standard for communicating color specification and quality control. They provide a common language for color so specifiers and manufacturers can be sure they understand the customer’s expectations and reproduce those colors, even if they’re a world away.

10 Tips for Visually Evaluating Color

Does your quality control program include visual evaluation?

If not, it should.

No matter your industry, judging color is more than just measuring samples with a color measurement device. Just because a spectrophotometer says your color is within tolerance, doesn’t necessarily mean it will look right to the human eye.

To minimize customer rejects, your color control process needs to include visual evaluation in a light booth. This is especially important if you’re producing different parts for the same product, because they need to match in the factory, as well as outside, in a fluorescent-lit store, and wherever else they’ll be seen once they enter the world.

Today we’ll review visual evaluation best practices to ensure your quality control program is the best it can be.
