Abstract
A method of printing an image on a substrate by applying to the substrate a film which is chemically activated by heat, and scanning the film by a beam of radiation according to the image to be printed, to chemically activate the film by heat and thereby to produce a pattern in the film according to the image scanned. The film includes a reagent capable of undergoing a redox reaction when heated in the presence of another reagent present with the film when scanned by the beam, to produce the redox reaction between the two reagents.
