Chronological study of seals of Chinease painterscalligraphers and collectors in Japanese collections

我们对大阪市博物馆、京都国立博物馆和东京国立博物馆收藏的中国书画作品进行了研究，这些作品对本项目具有重要意义。首先，我们用6*4.5大小的相机拍摄了所有作品的黑白总图。接下来，我们拍摄了艺术家和收藏家在作品上的印记的实际大小的黑白照片。为了更容易识别墨水的颜色，必要时还拍摄了6*4.5彩色照片和35 mm彩色幻灯片。这些照片中每个印章的实际大小都印在卡片上，并由艺术家和收藏家进行分类。每个印记的真实性和日期也被考虑在内。为了更准确地确定印章的年代和年代，在三年研究的基础上，有必要进行更大规模的印鉴汇编。有鉴于此，对研究材料进行了分类，并用计算机进行了记录。

We catrried out a research on Chinese paintings and calligraphic works in the collection of the Osaka City Museum, Kyoto National Museum and Tokyo National Museum which are important for the present project. First, we photographed in black and white general view of all the works with 6*4.5 size camera. Next, We took actural size black and white photographs of the seal marks of the artists and collectors on the workd. for easier identification of ink colors, 6*4.5 color photographs and 35mm color slides were also taken when nessesary. An actual-size print of each seal mark in these photographs are paseted on cards and classified by the artists and collectors. Authenticity and dates of each seal marks were also consideres. For more accurate dating and chronology of seal marks, compilation of seals in a much larger scale based on the three-year research is necessaryy. In view of this, the research materials were classified to be documented with computer.
