This type of T-shirt printing is where it all started...your design cut from a solid colour vinly and layored up with different colours. The reliability of this type of printing had been questioned over the years however, if the right vinyl is applyed in the correct way we have nothing to worry about.
It's easy on the wallet and quite often a logo in one colour is the most effective.
Vinyls can come in a variety of different effects from metalics, to fluffy, carbon to glitter and now even black board or white board so you can write on them!
You won't get a stronger colour than a solid vinyl!
