At Nuwave, unlike most other makers of these things, our graphics are printed onto blockout textile rather than traditional vinyl. Why?
We believe the quality of a fabric graphic is so superior to a vinyl graphic, that that on its own is good enough reason - also dye-sub printing, with water based inks, is a far better ecological story than vinyls which are printed with far more aggressive solvent, latex or UV inks.
What are these superior quality features of the fabric graphic? 
One look at the photograph above tells the story - The banner on the left, a fabric roller banner made by Nuwave - totally flat, no curling edges so often seen on vinyl banners, no light reflecting off the shiny vinyl, and almost impossible to damage. Dye-sub printed textile is near impossible to scratch or damage.
By contrast the banner on the right, with a vinyl graphic has all the classic signs - curled edges, light reflecting off the graphic and classic signs of damage and creasing.
We think it is clear the the fabric banner is the far better option - we hope you agree.
