Understanding linescreen, volume and geometry, and how they work together, is the beginning step to consistent, quality printing. You may have certain artwork or a certain account whose print dynamics always seem to be a problem when running on press. The simplest solution could be that you are running a plate, anilox and ink combination that is not made up of the optimum materials for that application. Locking down your anilox selection is where to start.
How does linescreen play a role in the anilox? The linescreen provides the cell opening on the surface of the anilox. The linescreen is defined by how many cells are present per linear inch on the roll (lpi). A properly selected linescreen does two things: It allows for distribution of volume without compromising cell quality, and it supports the printed dot. When running artwork like 4-color process, a high linescreen is used to help support the low dot percentages, also known as highlight screens...
