Negative score
It is used to score the material from the rare part of the cut during the one-pass through the machine.
Negative score may also be a solution for tearing a packaging box easily as well as for negative bending. Advantage of a negative cut is that it can be used for folding board, laminated board as well as for corrugated board up to the type of the 5-layer board.
