Creasing Matrix

Creasing Matrix are used, combined with steel creasing rules to create a folding line in paper or cardboard. The folding line allows a perfect fold without cracks in a printed document or box.

The creasing matrix are mainly used on typographic presses.

For this product there are three different types available:

The standard creasing matrix is used when a single folding line needs to be created or when enough space between 2 folding lines is available.
A= channel width
B= is the height of the channel

 

 

The offcenter channels are used when 2 folding lines need to be placed close to each other. The offcenter creasing matrix is narrowed on one side.
C is the width of the narrowed plastic strip

 

 

The Mini channels are used when 3 or more folding lines need to be placed close to each other. The mini creasing matrix is narrowed on both sides.
C is the width of the narrowed plastic strip

  

On the underlying pages you can find all the creasing matrix. The Nr. of the channel that you need is determined by the thickness of the paper/cardboard (or the weight). You can use to following formula to determine what type of creasing matrix is needed:

(Paper thickness (in mm) x 1,5) + thickness of the steel creasing rule (in mm).

The result is then compared to the width of the channel (A) of the available creasing matrix.

For example (paper thickness 0,4 mm x 1,5) + thickness of the rule 0,71 mm (2 pt) = 1,31

Attention: this formula offers you a recommendation. Certain qualities of paper/cardboard may show different results. We cannot be held accountable for unsatisfactory results. When in doubt on what type of matrix to use, feel free too contact us, without any obligation.
