Ensure The Closedness Of The Ink Supply System

Ensure that the ink supply system is closed, and it is best to install a filter device (120 mesh or 140 mesh) at the ink inlet, which is very necessary. For ceramic anilox rollers, you should also pay attention not to be close to the heat source. Too high temperature will cause the ceramic layer of the ceramic anilox roll to fall off. How well the anilox roller is maintained can be judged by observing its appearance and inspecting it with a magnifying glass. A well-maintained anilox roller has a clear surface, consistent color and gloss, no obvious stains, and no obvious scratches or damages are observed under backlight; while an improperly maintained anilox roller has a fuzzy, dim surface and obvious stains. , If there is a scratch or damage, it can be seen in backlight. Observing under a high-power magnifying glass, it is clear at a glance whether the cells are clean or not. Manufacturers with conditions can also use a densitometer to detect and evaluate the density of the printed area, which can determine whether the anilox roller is cleaned.
