Printing Materials >  Triaprint


Triaprint, a new alternative to tradtional Correx and fluted polypropylene, 100% recyclable and enhanced rigidity.

Unlike a fluted board which only offers rigidity in a single direction Triaprint has a unique inner cell structure giving it superb rigidity in all directions not just against the flute. This gives Triaprint an advantage in strength over a traditional Correx board. Its unique cell structure also means it is incredibly lightweight and resistant to pressure.

Triaprint is also 100% recyclable making it a fantastic environmentally friendly external signage board. Both sides of the Triaprint sheets have been specially formulated for digital printing.

Spot WhiteWhen working with colour variations of Triaprint we can still print direct to surface in full colour underpinning your print with a spot white to ensure it is as vibrant as it would have been if printed on a white sheet.

Spot White (Clear Material) – With clear materials a white ink is often required to add the ability to include white areas of a design or to underpin CMYK printing to give it a denser appearance.

White Flood Triaprint can be printed with a full coverage white ink layer to back up a colour printed design giving you the appearance of a white background. This is popular when printing in reverse.

Backlit Mode When producing light box graphics, or prints that will be illuminated from behind we can print in backlit mode to increase the saturation of ink to ensure your design retains its intended look and finish.
