Abstract: The invention relates to a method for making articles having a veined aspect that includes the steps of (a) extruding a layer of substantially transparent PMMA including pigmented granules in a first extruder, (b) extruding a polystyrene layer including a foaming agent in a second extruder, wherein the extrusions of steps (a) and (b) are carried out simultaneously as a co-extrusion.

Abstract: The invention relates to a method for the continuous, single-step application of a decoration to at least one face of articles made from an extruded- or foamed-plastic material. The aforementioned step comprises: (i) the embossing of at least one face of the article, by passing the article under an embossing roller which is equipped with a relief groove; and (ii) the printing of said at least one face of the article with the transfer of an ink from a composite film with transferable ink. The printing step is performed concomitantly with the embossing step with the same embossing roller which is made form an elastic material and which is heated to the surface softening temperature of the plastic article. The invention also relates to a device for decorating extruded- and foamed-plastic articles in a single step, to the articles thus decorated and to the use of the method and the device.
