Des résines liquides 2,3 ayant chacune une couleur différente sont laminées par injection dans un moule de manière qu'au moins deux couches soient formées. On passe ensuite un outil en forme de peigne 1 dans les résines liquides laminées, les dents de l'outil étant en contact avec le fond du moule. Puis, on fait sécher les résines pour obtenir un marbre artificiel à rayures. Suivant le procédé de production du marbre artificiel, on peut former des rayures nettes en continu dans son épaisseur, lesquelles ne disparaissent pas quand on meule la surface du marbre artificiel.
