Premium NeverTear - Strength and durability without the use of lamination

Finishing – Post print

Die Cutting
This material can be die cut in various amounts depending on the thickness.
TIP – Keep retention points as small as possible and all internal corners should be radiused Refer to www.zund.com to view an in-line cutter manufactured by a company called Zund which is programmed to cut shapes automatically.
Punching
All thicknesses can be punched to achieve various shaped holes but rounded holes are recommended.
Perforating
The thinner sheets can be perforated using a perforating wheel but the thicker sheets will need to be perforated using a die cutter.
TIP – Slots should be long with very short ties
TIP – Perforation should run off the sheet
Drilling
Can be carried out using a hollow, high speed drill. The drill should be lubricated to reduce friction (and, therefore, heat build up).
TIP – Keep dwell times short
Guillotining
All thicknesses can be guillotined. Sheets should only be guillotined after printing.
Folding
The material can be folded using a folding machine but it will not fold flat – rather as a 'V' shape.
Scoring
It is not recommended to score the sheet since this may weaken the surface and initiate a tear.
Varnishing
Varnishing the printed polyester material achieves a high gloss finish and further protects the print.
Lamination
Lamination may be necessary to achieve a finished product which is extra thick - for example, a credit card.
It may also be necessary to laminate the printed polyester material when is it to be touched continually by fingers, for example, key pads.
