What is creasing matrix?
Creasing Matrix is a consumable device which is used in manual or automatic die-cutting machines to impart a perfectly registered crease in solid or corrugated board. This ensures maximum stability at conversion stage and a flawless appearance.
Why use creasing matrix?
Before the invention of creasing matrix, skilled operators used to make creasing matrix by hand (this is still practiced around the world even today). They would use a sheet of cardboard or a presspahn board (layered sheets of board stuck together to get the desired thickness). This was then stuck to the cutting plate. Once stuck, the ‘contours’ of the cutting die rules were copied using carbon paper and the corresponding contours were then cut into the material using a sharp knife.
Such a technique is extremely time consuming (depending on the complexity of the design) and gives poor results on more complicated designs as very large tolerances are used. Additionally, stripping the plate of the material after the job has been run is also very time consuming. Channel Matrix were the first company to introduce creasing matrix to the world and have, over the past 50 years, been developing new matrices as more technological advancement has been made to die-cutting machines. This has resulted in more complex packaging designs becoming possible.

Trouble shooting for creasing matrix
The following are a list of the most common asked questions – we hope the following answers help!! If not please contact us for further assistance.
A. Creasing rule is likely set too high, there we recommend you lower the rule height.
Q. Why does the crease crack at the edge of the fold?
A. It is possible the creasing rule is not in correct alignment with centre of matrix, so we would suggest replacing matrix, if making ready by hand then trim the edges.
Q. The crease cracks at two edges of fold, how can I remedy this?
A. It sounds like the channel width is too narrow, therefore we recommend you use a wider channel.
Q. The definition of the crease is not as good as I had hoped.
A. It sounds as though the creasing rule to be too low or the channel is too wide, in which case we would recommend increasing height of rule with C&T Shim tape or using a narrower channel.
Q. Why does the bead collapse at the back of the crease?
A. It sounds as though the creasing rule may be set too low, so again increase height of rule using shim tape.
Q. I get a poor crease definition when I use a low grade board – how can I improve results?
A. This is a common problem, it is likely that the channel depth may be too shallow. Try using a deeper matrix.
Q. I have trouble fitting the locator onto the creasing rule, what is your solution?
A. It is one of 2 reasons that you experience this problem. Either i) you have the incorrect locator size (e.g. a 2pt locator on to a 4 pt creasing rule OR ii) the creasing rules are damaged or rusty. We would recommend the following course of action: i) use a wider locator and ii) either replace the damaged rules or, if rusty, lubricate with oil or wax (a candle works perfectly!)
Q. The creasing matrix doesn’t stick properly to the cutting plate, please advise what to do?
A. It is likely that the cutting surface is dirty or oily, therefore we would recommend cleaning the surface thoroughly to remove the contamination.
Q. I frequently experience bruising at the edges of the creases, how do I overcome this?
A. It sounds as though there is too much pressure being applied, the best solution to maintain the crease definition would be to rub down the matrix with sandpaper or chamfer the ends of the matrix.
