Our services 

include the design and printing of door signs and plaques, which can be personalised with your own text, images and logos if required.

They are made using a sublimation process,  which is very different from screen printing, print-cut vinyl or direct to substrate printing where text and graphics sit on the surface. The sublimation ink is infused into the surface itself and will not peel or crack.

The Substrate

Aluminium is a great medium for all types of signs and plaques. For sublimation purposes it is formulated with a special coating that allows ink to be infused into the surface, it is rust proof, rot proof and weather resistant.

Sublimating onto metal is a great way of reproducing images and text. The sublimation process itself goes from a solid to a gas and then back to a solid, skipping the liquid state.

The image or text is first printed onto a special transfer paper and then is adhered to pre-treated aluminium.
