Abstract
A recording method comprising the consecutive steps of: PA1 (1) image-wise projecting droplets of liquid, called ink, containing halide ions, onto a receiving material containing at least one substantially light-insensitive silver salt, said ink and/or receiving material containing at least one reducing agent for said silver salt, PA1 (2) uniformly photo-exposing said receiving material to form silver nuclei from silver halide obtained in step (1), and PA1 (3) heating said receiving material during and/or after said photo-exposure thereby forming a silver image in correspondence with the area wherein said ink has been deposited on said receiving material.
