Optical printing system

A printing apparatus for printing on a photosensitive pressure developable recording sheet (415) which has a layer comprising a plurality of microcapsules, each of said microcapsules enveloping: a first component which changes colour when reacted with a second component, and a third component which...

Beschreibung
Zusammenfassung:	A printing apparatus for printing on a photosensitive pressure developable recording sheet (415) which has a layer comprising a plurality of microcapsules, each of said microcapsules enveloping: a first component which changes colour when reacted with a second component, and a third component which changes the mechanical strength of said microcapsules when exposed to light, said apparatus having a laser oscillator 413 so a pattern can be projected onto said recording sheet to light via rotary mirror lamp 402 and optics 403-405 for projecting light reflected off a manuscript 401 (or transmitted through a photographic film) whereby a latent image of said manuscript or said photographic film and/or said pattern image may be formed on said recording sheet; and rollers (416) for rupturing those of said microcapsules having a relatively low mechanical strength.
