A decorative web or sheet of plastic material is obtained by spraying plastic material of different color and/or structure onto a carrier web by means of nozzles, the carrier web and the nozzles being movable in relation to each other, such that the nozzles can be placed over different, predetermined areas of the carrier web. The relative movement is controlled by means of a computer programmed with the desired web or sheet pattern. A suitable installation for carrying out the method has means for transporting the carrier web in one direction and carries nozzles which are movable parallel to the carrier web in two planes at right angles to each other. By means of the nozzles, plastic material is sprayed onto the carrier web in predetermined areas and to the desired thickness. A decorative web or sheet thus obtained consists of pattern-forming areas of plastic material of different color and/or structure, which extend throughout at least a substantial part of the thickness of the web or sheet and are fused together along adjoining peripheral edges.
