Image output technology

Once an image has been captured and stored, whether it is in analog or digital format, for it to be useful in the future there must exist some way of re-rendering it. It is hoped this will be in a manner that is imperceptibly different from the original. Because it is usually impossible to render an image in identical form to the original, numerous decisions need to be made concerning which attributes are the most important, in terms of image archival quality and diagnostic accuracy.
