Who's Afraid of the Big Bad Roll?
2. THE FEATURES
Speed may be the defining feature of jumbo rolls, but it’s far from the only feature. If the finished forms aren’t up to spec, it doesn’t matter how quickly they were printed, and suppliers know that, offering everything from UV-curing to laser-guaranteed paper to ensure roll quality. “Many of our presses we run jumbo rolls on are equipped with inter-stage UV, and the advantage of that capability is it ensures inks are cured,” mentioned Simon. “As you run into a jumbo roll, with the pressure that’s involved in the roll—and the pressure must be maintained—you need to make sure the ink is cured. You cannot afford to have ink offsetting as the roll is wound on the rewind of the press.” Simon explained that this is crucial for accuracy, as corporate logos and other items must match exactly in color. “They can’t be a shade or even a half a shade off, or they may be rejected,” he said. UV curing guards against this ink discoloration.
