Frequently Asked Questions - Please choose a question:
What style of Shreiner Matrix should I use for my job?
There are many different styles to choose from and each has it’s benefits, whether it be material, shape, or price.
- Shreiner Metal - Shreiner Metal is the original and most widely used style of matrix. Shreiner Metal is an excellent option for short runs on cylinder and clamshell type presses. I recommend this style of matrix to most printers that are running a few thousand impressions on cover stocks, metal base is both durable and economical for these types of jobs. The major shortfall of metal base is size limitations. If one should run into a situation where they would need to make use of reduced bead creasing the lack of available sizes would make it difficult to achieve this. The major problem is someone can not change one dimension without changing the other. For instances where reduced bead creasing must be utilized a plastic or fiberboard matrix would be best.
- Shreiner Fiberboard - Fiberboard matrix has become very popular with folding carton plants over the years, and for good reason. There are many advantages to using fiberboard matrix, not only for folding carton, but for everyone. The main advantages of fiberboard are the size options and the ability to skive it into different shapes. Fiberboard comes in many different height and width combinations, which makes it ideal for reduced bead creasing. When kept in an ideal state it is extremely durable, especially types with the “glass top”, such as Shreiner Fiberboard. The ability to easily skive the material is excellent for tight areas where scrap tends to get caught up on the matrix. I recommend this matrix to anyone that has medium to long runs. This matrix is well suited for any type of press, especially autoplatens. The down-side? Price and material. Fiberboard matrix is the most expensive to purchase and to manufacture. The product is worth the investment to those that have long runs, but probably not for smaller, short-run shops. The fiberboard material itself can also be a down-side. Fiberboard is a paper product, and as such can be vulnerable to moisture, or a lack thereof. Too much moisture can cause the product to swell and change dimension. Lack of moisture can cause the fiberboard to delaminate and separate during a run.
- Shreiner Profile - The last style choice for matrix is plastic. Plastic matrix is a style that has been gaining popularity among die-cutters over the past couple of years. Shreiner Profile in particular has been gaining tremendous popularity for just being introduced within the last couple of years. Shreiner Profile has a bevel that is rolling from one side of the cutting plate to the other, as opposed to the traditional chamfered edge. Shreiner Profile shares many of the positive attributes of fiberboard. There are a multitude of size options for reduced bead and traditional creasing, it is extremely durable, it has tight tolerances, and is cost effective. I recommend this style of matrix to everyone. It works well for any length run, any style press, and the general price makes it affordable to everyone. The most common negative I hear about plastic matrix is you can not skive it easily. One can skive this material, but not with the same ease of a fiberboard.
