We can expect a variety of hard copy systems to emerge with digital photography, and Aztech Systems Ltd of Singapore has an alternative to the inkjet printer in the shape of its Desktop Photo Developer, which uses technology licensed from a US company, Cycolor Ltd. This technology, called Cylithography, produces photo-sensitive polyester film that contains light- sensitive microcapsules. Digital snaps can of course be produced as and when required even when the memory cartridge is not fully used. Aztech says it aims to build capacity for 1million units in the first 12 months, starting next quarter. Aztech has two models: an internal one which fits into the 5.25 disk drive bay of a personal computer, and an external one. It gives the size of resulting prints as 3R, which sounds as if it is something like 5 by 7 or 5 by 3 but it will have versions printing larger photographs later. The company gave no indication of a price for it.
