激光打印字迹材料是档案文件的重要组成部分,但是容易受温度、湿度和光照等外界环境因素的影响。文本通过老化性能试验,研究了激光打印字迹的耐干热、耐紫外光照、耐水浸、耐酸、耐碱等性能,并对激光打印字迹的长期保存提出了建议。 Laser printed writing materials are an important part of archival documents, but are susceptible to external environmental factors such as temperature, humidity and light. Text Through the aging test, the characters of laser printing, such as dry heat resistance, ultraviolet light resistance, water immersion resistance, acid resistance, alkali resistance and so on, were studied. Some suggestions for the long-term preservation of laser printing script were put forward.
