Abstract An improved structure of roller is made up through cutting fine slots on the surface of roller, colouring and grinding its external diameter to needed size. As a result, the colour of roller itself is exposed and the residual colour is stayed in its slots. Its advantages are easy manufacture and easy control of strip size.
