Abstract

In a method for full format imaging, a solid continuous film of a dispersion imaging material is provided on a substrate and it disperses into a discontinuous film comprising space globules and free space therebetween through which free space light can pass where it is subjected to a short pulse of high intensity non-coherent radiant energy in an amount sufficient to increase the absorbed energy above a certain threshold value. The short pulse of high intensity non-coherent radiant energy is applied to the solid continuous film, through a mask, simultaneously and substantially evenly in a full format pattern to a plurality of areas thereof to cause simultaneous and substantially even dispersion of the continuous film in those pattern areas into a discontinuous film comprising the spaced globules and free space which are substantially evenly distributed in those pattern areas and through which free space light can pass. A stable finished full format image of said discontinuous film in the solid continuous film corresponding to the full format pattern of energy is rapidly and inexpensively produced and which has high contrast between the imaged and unimaged regions.
