Perforating Defined

Perforated paper is paper that has had holes or cuts punctured into it. One common example is often seen on invoices that have "tear off" return payment stubs. The number of actual punctures per inch - referred to as teeth per inch, or tpi - determines both the appearance of the torn edge and the ease with which the paper is separated at the line of perforation.

There is no "standard rate of perforation", just as there is no standard "use of perforation". For example, the perforation commonly found on the return receipts of your local utility invoices is commonly perforated at a rate of 40 teeth per inch. Generally, perforation at a rate of 30 or more tpi is referred to as micro-perforating.

Conversely, some perforating is designed to render paper "tearable" but not too tearable. For example, perforation between raffle tickets and their corresponding tear off stubs are often perforated at a rate of 12 tpi, assuring that the stub does not come apart too easily; either during normal handling or when being printed. Other examples of perforated items that are not necessarily micro perforated include auction cards, movie tickets, valet parking slips and inventory tags used by manufacturers.

Scoring Defined

Scoring refers to "creasing" paper so that it folds easily and neatly. Scoring is accomplished by creating an impression along a line on which a sheet of paper will eventually be folded. Both the depth and width of scored lines, or impressions, can be varied according to need. Scoring provides a professional appearance to the item to be folded that is neat and crisp. It's also a lot easier to fold.

Examples of scored paper include bulletins, memorial folders and invitations; without scoring, these items would be subject to fold unevenly.

Die-Cutting Defined

Die-cutting is a process by which paper is impacted by a stationary die through the use of a letter press machine. A "die" is a combination of perforating pins, slicing blades and/or cutting edges, which, when forced down against a sheet of paper, creates a "punched out paper product". One example of a die cut product is a door hanger, which includes perforation, the cutting of holes, and the rendering of a slit so that the hanger can be easily placed over a door knob.

Dies are used whenever regular perforating and/or scoring blades cannot satisfactorily accomplish the task. Examples of die-cut paper products include our door hangers (the hole that is cut to fit around the door knob), Chinese auction cards (due to the complication of the configuration). Normally, any curved line or one that starts and stops before the edge of the paper may require the use of a die.

Our prayer cards and holy cards are die-cut due to the very fine and exact placement of the perforation required to accommodate both clean edges and exact registration of printing text and graphics multiple times on the same sheet of blank prayer cards.

Dies are made to order for any unique task. Call 800-364-1509

NOTE: Minimum order for jobs that require manufacturing a new die is 5,000 sheets.
