The Leprechauns Made Me Do It, St Patrick's T-Shirt, Novelty T-Shirts great gift
 
The Photo quality images just pop in this relaxed fit T-shirt. With set-in sleeves and a rib crew neck collar printed using a technique called Sublimation. Dye Sublimation printing is a process whereby full colour images, text and other graphics can be transferred onto a receptive item. The process relies on a specialised ‘dye sublimation’ ink, which when heated changes from being a solid dye to being a gas, without passing through a liquid stage. Taking this a step further, if this gas encounters polymer fibres as it moves, it will penetrate those fibres, permanently dyeing them. 
 
The effect is rather like that of tattooing. The surface of the substrate is smooth and the transfer print cannot be felt (unlike with a screen print), instead becoming part of the surface. This provides a totally durable result that will not fade or crack.
