A photosensitive recording medium having a multiplicity of microcapsules formed on a substrate, and a developer material, each microcapsule having a photosensitive resin and a chromogenic material which reacts with the developer layer to form a colored image spot. The microcapsules comprising a plurality of microcapsule groups which are sensitive to radiations having different wavelength bands, or which are sensitive to different intensities of the radiation. An image recording system is provided with an illuminating device for generating radiations of different wavelengths falling within the wavelength bands of the microcapsule groups, or a radiation of variable intensity. The recording system has a selector for selecting at least one of the radiations of the different wavelengths, or one of the intensity levels of the radiation, in order to adjust the contrast of the images formed on the medium, with respect to non-image areas on the medium.

An image transfer system for transferring images from an original to a photosensitive recording medium, the image transfer system comprising: a photosensitive recording medium comprising a multiplicity of microcapsules for at least one color, said multiplicity of microcapsules including a plurality of microcapsule groups for each of at least one of said at least one color, said multiplicity of microcapsules of said plurality of microcapsule groups being substantially evenly distributed over a surface of said recording medium, said plurality of microcapsule groups being sensitive to a respective plurality of radiations having respective different wavelength bands; an illuminating device for selectively irradiating said original with a plurality of exposure radiations having respective different wavelengths each of which falls within one of said different wavelength bands; and selector means connected to said illuminating device, for selecting a number of said plurality of exposure radiations, said number being between one of and all of said plurality of exposure radiations, so that a corresponding number of said plurality of microcapsule groups is image-wise exposed, so as to adjust a contrast between the transferred images on said medium and non-imaged areas on the medium by varying said number.
