In einer perfekten Welt sollte man in der Lage sein, Farbe in die Druckmaschine zu geben, einen Auftrag auszuführen und Farbkonsistenz zu erreichen. Leider verschwenden Flexo- und Tiefdruckbetriebe jedes Jahr Farbe, Bedruckstoff und Druckmaschinenzeit bei dem Versuch, die richtige Farbe zu finden. Obwohl die Fortschritte in der Technologie es einfacher gemacht haben, Farbgenauigkeit zu erreichen, gibt es immer noch Variablen, die die Farbe beeinflussen. In dieser dreiteiligen Serie stellen...

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) follow...

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....

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...
