Digital images can now be produced by a number of different imaging technologies. Ink jet has emerged as the most popular method for printing digital photographs. This is a direct result of the developments in inks, printers, media, and software during recent years, providing high quality images which come close to those produced by silver halide technology.One further challenge, for ink jet systems, is to match the image permanence of silver halide. Photographs produced by silver halide technology, generally have greater image stability and can be archived for many years, with little sign of any deterioration in image quality. The stability of ink jet images, in different environments, can however, be a problem. The influence of the environment on image stability will be considered.
