Increasing numbers of galleries, museums and archives are including ink jet printed materials into their collections, and therefore displays. There is evidence that the instability of these prints is such that images can suffer deterioration in print quality or in extreme cases, a loss of information over an extended period of time. This is shorter than the period typically required for perceptible deterioration to occur in other paper-based artworks. The image stability of prints is affected by a number of factors some of which have already been studied. However the role played by the solvent in the loss of image quality has yet to be explored.This research will investigate the effects of solvent content which may increase/promote the loss in image quality of the hard copy prints when stored or displayed under a range of temperature and humidity conditions.Building on an extensive literature survey, laboratory based research will be carried out on a range of contemporary ink jet printed materials. The materials selected will include all types of ink jet systems that use process colour inks on both swellable and non-swellable substrates, including fine art digital print papers. Samples will be subjected to a variety of defined treatments designed to reduce or remove the solvent content. The extent of solvent removal will be established using fourier-transform infra red spectroscopy and thermal analysis techniques, and will be monitored for enclosed prints through gas chromatographic headspace analysis. Following these treatments, samples will be stored under defined temperature and humidity conditions that are intended to simulate conditions found in both well and poorly controlled archival and domestic environments. Some samples would be stored in the open, some contained within non-permeable envelopes; these will be subject to periodic monitoring. Some samples will remain within sealed enclosures until examination. Samples will be stored for up to two years.Changes in image quality will be assessed objectively from density, gloss and colorimetric measurements. The last will be carried out and compared on a macro and micro (sub-millimetre) scale. Optical and scanning electron microscopy will be employed to establish the movement, both lateral and vertical, of the dyes and/or pigments. Perceptible variations in print quality will also be assessed subjectively using panels of observers.Following analysis of the prints, recommended procedures for long term preservation of prints will be made which are relevant to heritage organisations responsible for the conservation and preservation of digitally printed artefacts.

越来越多的画廊，博物馆和档案馆包括墨水印刷材料，并因此显示。有证据表明，这些印刷品的不稳定是如此，即图像可能会在印​​刷质量上或极端情况下遭受损失的信息损失。这比在其他纸艺术品中发生的可感知恶化通常所需的时期要短。印刷品的图像稳定性受许多已经研究的因素的影响。然而，溶剂在损失图像质量中所扮演的角色尚未探索。这项研究将调查溶剂含量的影响，这些溶剂含量可能会增加/促进在温度和湿度下存储或展示的硬拷贝印刷品的图像质量损失。在一系列的温度和湿度条件下进行。建造对广泛的文献调查的广泛文献研究，将在实验室研究中涉及一项现代墨水印刷材料的范围。所选的材料将包括所有类型的墨水喷气系统，这些系统都在膨胀和不可舒适的基材上使用过程颜色油墨，包括美术数字印刷纸。样品将经过各种旨在减少或去除溶剂含量的定义治疗方法。将使用傅立叶转换红色光谱和热分析技术建立溶剂去除范围，并将通过气相色谱顶空分析来监视封闭的印刷品。在这些处理之后，样品将在定义的温度和湿度条件下存储，旨在模拟在良好和控制不良的档案和家庭环境中发现的条件。有些样本将存储在公开中，其中一些包含在不可渗透的信封中；这些将受到定期监控。一些样品将保留在密封的围栏内，直到检查。样品将存储长达两年。图像质量的变化将根据密度，光泽度和比色测量值进行客观评估。最后一个将在宏观和微观（亚毫米计）尺度上进行比较。将采用光学和扫描电子显微镜来确定染料和/或色素的侧向和垂直运动。印刷质量的可感知变化也将使用观察者的面板进行主观评估。遵循印刷品的分析，将进行长期保存印刷品的建议程序，这些程序与负责保存和保存数字印刷品的遗产组织有关。
