A method for forming latent images on a media sheet coated with micro-capsules. Each of the microcapsules contains a dye capable of coloring to either yellow, magenta or cyan and is curable by irradiating to one of blue, green and red light. The media sheet is successively exposed to blue, green and

A method for forming latent images on a media sheet coated with micro-capsules. Each of the microcapsules contains a dye capable of coloring to either yellow, magenta or cyan and is curable by irradiating to one of blue, green and red light. The media sheet is successively exposed to blue, green and red light to cure the micro-capsules. There is an interval of at least 5 seconds between exposure times of the blue, green and red lights.

A method for forming latent images on a media sheet which is coated with at least first micro-capsules which contain a first photocurable material, which is curable by light having a first wave length range, and a first color developing dye, and second micro-capsules which contain a second photocura

A method for forming latent images on a media sheet which is coated with at least first micro-capsules which contain a first photocurable material, which is curable by light having a first wave length range, and a first color developing dye, and second micro-capsules which contain a second photocurable material, which is curable by light having a second wave length range which is different from said first wave length range, wherein the first wave length range partially overlaps the second wave length range, comprising the steps of: (a) exposing the media sheet to light having the first wave length range, (b) stopping the exposure of the media to the light having the first wave length range; and (c) after an effective amount of time has passed to supply oxygen to the micro-capsules exposing the media sheet to light having the second wave length range.
