Perforation is a print technique where a series of holes are punched into paper or card, allowing a simple tear-off section that doesn’t damage the rest of your printed product.
Adding perf lines means the customer doesn’t need scissors to remove a section of your custom printed leaflet, flyer, loyalty card etc. It allows for customers to easily remove vouchers or coupons, whilst keeping the rest of the booklet.
We can add perforations to your printed products using a perf wheel or through die cutting. Which method we used will depend on how big a perforated section you need and how many products need the perf lines.
Whereas perforation is most commonly used to allow for easy tear-off removal, it can also be used in lieu of score lines for a flatter fold (e.g. for folded leaflets).
Before you add perforation…
Mark your artwork
When supplying artwork please show the perf lines as a series of dashes in a spot colour (most commonly magenta). These lines will be removed from the artwork before printing takes place.
Consider the paper weight of your printed product
Perforation isn’t recommended for paper weights of less than 135gsm for leaflets and booklets
Figure out how many perfs you’ll need
The basic perforation has just one line to create a single tear off sheet but this can be increased to several lines either vertically or horizontally. You might want to create tear off boxes by having your perfs running both vertically and horizontally or you may need your perfed line to be in the shape of an ‘L’ or ‘T’.
Tear out return form
Standard perfing or microperfing?
with standard perfing you tend to get a jagged edge when the section is removed – this is normal and generally won’t affect your product. However, sometimes you might want a cleaner rip with a neater edge; microperfing uses smaller holes for the perf line, which leaves behind a nice clean line when removed.
Using perforations on a glued pad
Perforations are commonly added to pads where a page is torn out, e.g. with NCR printing where the top copy of a receipt is given to a customer. Sometimes the glue isn’t durable enough to withstand multiple tear offs – so staples will need to added to the binding. Remember to add perf lines leaving a space of at least 20mm from the pad edge.
