UV - It's Good ... But Be Careful

Another important "don't" Flynn stresses is to not use silicone anywhere near the press, especially with combination printing. "Spray silicone can travel in the air and contaminate the ink, leading to laydown problems on the press," he said. A third important factor to keep in mind when printing with UV is to watch the pressure on doctor blades. "Don't use too much pressure. Excess pressure can lead to premature wear," Trexler said.
