The present invention relates to a method for the manufacture of a matrix and to a matrix ( ) thus manufactured, at least one surface section ( ) displaying a microstructure, which matrix ( ) is suitable for inclusion as a mould insert in a mould cavity or in a cavity, in a unit producing plastic components, in order to assign said plastic components an opposing micostructure in a corresponding surface section. An original ( ) with a surface section ( ) displaying a microstructure less than 500 &mgr;m is used in order to apply on this original layer upon layer of a material ( ) and/or mixtures of material producing a matrix, and thereafter the matrix ( ) is removed from said original ( ) or the material in the original is removed. A first layer of material ( ) applied on the original ( ) so that together with a number of additional layers of material, said matrix is formed, is selected having exceptionally good properties as regards the ability of the plastic component to release from the matrix after moulding, curing or polymerisation of the plastic material used, and exceptionally good properties as regards retaining the pattern on the microstructured surface section.
