Abstract

In a printing system for printing an image on a recording sheet, adopted as the recording sheet is a sheet coated with microcapsules on one surface thereof. Each microcapsule envelopes a first component therein while the sheet itself holds a second component. The color of second component is changed when mixed with the first component. The microcapsule further envelopes a third component which increase the mechanical strength of microcapsule when light is projected thereto. An image is formed on the recording sheet by selectively rupturing the microcapsules in accordance with the image to be printed thereon, and the unruptured microcapsules remaining on the recording sheet are then hardened by exposing a light thereto and thus the image printed on the recording sheet is fixed thereon.
