The fading of inkjet imagery has been the subject of many studies. This study follows on from one presented at the previous Archiving conference, expanding on the investigation of colorimetric changes during fading processes.The aim of this study is to illustrate the important issues to consider in the restoration of dye based inkjet images. As such images make their way into museum collections these issues become important when preserving the cultural heritage. This study will also identify where inkjet media and ink technology is not yet up to the task and illustrate the archival properties and colour science of such imagery.The influence of media type, printed colour and ink load are the primary variables explored. The correlation of the fading characteristics with ink coverage and penetration are also included.Whilst this study picks on a single ink set as an example, two very different types of media have been studied in order to illustrate the wide range of results that can be achieved. This will emphasise the importance of the inkjet media in both the fading process and in any restoration envisaged.The characteristics of the cyan, magenta and yellow in this ink set will be shown to be very different. The implications of these differences in the fading of these images will be explored. In addition to pure CMY colours, the effects on RGB combinations will also be considered.Whilst this study concentrates on the light fading of a dye based ink set the results are compared and contrasted with gas fading and light fading of pigmented inks.
