Abstract
The invention relates to a method of patterning a layer formed from a fixable material such as photopolymer on a surface in a desired pattern. The method involves coating selected areas of the substrate with an adhesion promoter and subsequently coating the fixable material. The fixable material is then fixed, for instance by curing by exposure to UV radiation. The adhesion promoter is adapted to have a surface energy which is designed to adhere to the substrate or selected areas thereof and also to the fixed material such that fixed material may be easily removed from areas of the substrate not coated with adhesion promoter but retained in areas where the adhesion promoter has bonded to the substrate.
