ABSTRACT
Image stability is a vital element in professional photography. Clients and commissionershave a right to expect the work they have purchased to last a reasonable time – either asmany years as possible, or at least sufficient for its intended purpose. Over time a great deal has been learnt about the permanence of prints on silver halide papers. Some methods of
printing, both analogue and digital, are not long-lasting, in other words they will fade within a
relatively short period of time. Less is known about the permanence of digital prints but it is
clear that for any degree of permanence archival inks must be used at the printing stage.
