Abstract

Methods are provided for producing relief images having improved fidelity and resolution. The methods comprise positioning an image-bearing negative transparency closely adjacent and substantially parallel to a layer of a photocurable material; positioning on the other side of the negative from the photocurable material and in substantially parallel relationship thereto; providing a collimator that has first and second opposing major faces and comprises at least one cell that extends from said first collimator face to said second collimator face and is defined by at least one surface that substantially absorbs actinic radiation incident upon said surface; positioning said collimator opposite a photographic negative that is adjacent a layer of photocurable material; and passing actinic radiation through said collimator for a time sufficient to form a latent relief image in the photocurable material.
