Print Issues With LongCell

Doctor blade too small

Because of the LongCells, the doctor blade can be too small and will not cover the entire cell. As a result, the ink can flow back when the doctor blade passes the cell wall (1).

LongCell Versus 60° Hexagonal Cell

Support of the roll

With the 60º hexagonal cell, the dot is supported by all the cell walls. For the LongCell the dot is only partially supported. When the exact same screen count is used, it might be possible that 30-60% fewer cells are available to support the dots. This depends upon the Cell angle.
