Have you ever sent out a job that passed your inspection, only to have the customer reject it for out-of-tolerance color? You recheck the data and the instrument says the color passed the agreed tolerance… why is the customer saying it doesn’t? We get a LOT of these conflicting measurement calls in technical support.
The solution is simple – document a color control program that clearly defines how to assess color, then make sure everyone (including your customer) follows it. Today we’re sharing what you need to include in your program so you can begin working with confidence.
In a perfect world, you should be able to put ink in the press, run a job, and achieve color consistency. Unfortunately, every year flexographic and gravure printing operations waste ink, substrate, and press time trying to get color right.
Although advancements in technology have made it easier to achieve color accuracy, the variables that affect color still exist. In this three part series we’ll share over two dozen reasons your color might be wrong at press side. Today’s topic looks at issues that can affect your color measurement instrument and substrates.
Reflective surfaces and metallic inks are very popular for printing and packaging applications. Consumers love the look; but for printers, these substrates and inks are expensive and make color control a challenge.
Today we’re taking a look at the measurement options available for controlling these very marketable print and packaging applications to help printers and converters meet brand owner expectations and maintain the highest possible quality output.
In a perfect world, you should be able to put ink in the press and run a job. Unfortunately, there are so many variables that affect color that printing operations often waste thousands of pounds of substrate, and thousands of dollars in press time, making adjustments.
Advancements in technology have made it easier to measure color, but the variables still exist. To help you over come them, we’ll be featuring a series that points out many of the reasons your color could go wrong at press side.
We’ll start with five tips for using your spectro.
Many print shops use more than one color measurement instrument, especially for cross-media color reproduction. But if you’ve ever measured the same color with different instruments, you’ve probably noticed that the numbers don’t always match.
Why is that?
Spectrophotometers measure color by capturing the ratio of reflected or transmitted light from the surface of the sample and comparing it to a known reference standard. The result is a spectral fingerprint for that color. But since calibration standards and reference databases vary slightly among models and manufacturers, the same color sample can produce different spectral fingerprints.
If your shop is using more than one instrument, which numbers do you believe and how do you create standard operating procedures?
This is the issue that prompted X-Rite to introduce the XRGA Graphics Art standard for factory calibration. It not only solves this metrology issue, but also incorporates new advances in color technology and the latest ISO standards.
