Abstract
Apparatus for utilizing microencapsulated media material includes a cartridge which contains a supply of the material, including a supply spool. The supply spool is wound as a two-layer sandwich which includes a donor web carrying the microencapsulated photosensitive material would in face-to-face relation with receiver material, in which the donor web forms the radial outer layer of the composite and the receiver material forms the radial inner layer. The donor web is formed with a clear base through which the photosensitive layer may be imaged, by drawing the composite from the spool past an exposure station formed as a slit in the cartridge. Thereafter, the composite is processed between a pair of developer rolls, one of which is formed as part of the cartridge. The donor web is then wound on a spool in the cartridge while the receiver material, carrying the image, is delivered from the cartridge. The receiver material may be glossed while it is within the cartridge by glosser apparatus contained within the cartridge. Additionally, the cartridge may contain means for treating the fumes of glossing.
