Why your Color Might be Wrong on Press: Instrumentation

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.

XRGA: X-Rite’s Graphic Arts Standard

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.
