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.
