ABSTRACT:
There is disclosed a syntehtic plastic sheet material having differentially colored bands made by a method which utilizes an extrusion die block having a chamber in which is disposed a pair of sleeve members. The matrix resin is supplied to the die block chamber and the differentially colored matrix resin flows towards the discharge openings from the sleeve members and encapsulates the differentially colored resin issuing therefrom. The bands of differentially colored resin are deposited at two different depths within the matrix resin with the bands at one depth being disposed in a first angular orientation and the bands at the second depth being at another angular orientation so that the bands appear to intersect and provide a grid pattern.
