  • Polyester: a polymer whose monomers are linked by ester bonds

Confused? Don’t worry. It’s easiest to focus on the specific qualities that set PET apart from its rivals. Let’s take a look!

Pro: Doesn’t Curl

Whether at the printing phase or the display phase, this quality is particularly advantageous. PET lays flat and hangs flat, even after being rolled. This means that it is not reliant upon traction. Clients will tend to prefer PET for:

  • Indoor displays that will be viewed close up
  • Free-hanging displays
  • Pop-up displays

PET does not require lamination, and printers will find that the flatness of the material allows for complex and intricate printing jobs.

Pro: No Edge Finishing Required

Smooth and supple, PET forms neat, sealed edges. This increases the printable surface area, guaranteeing the best value for money. The lack of edge finishing is ideal for reducing wastage.

Pro: Sharp Detail

PET can be manufactured to have excellent white point and overall optical clarity.

Con: Indoor Use Only

This substrate is designed to display up-close, detailed prints in indoor areas and display windows. For big, outdoor prints, PVC is the answer.

Con: Ink Compatibility

PET is only compatible with Solvent, Eco Solvent and UV inks. This offers less choice than alternatives such as PVC. However, the smoothness of the surface means that the printing quality is exceptional, particularly when viewed up close.
