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

我们对大坂市立博物馆、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，这对本项目很重要。首先，我们用6*4.5尺寸的相机拍摄了所有作品的黑白白色全景。接下来，我们对作品上的艺术家和收藏家的印章进行了实际尺寸的黑白白色照片。为便于识别油墨颜色，必要时还拍摄了6*4.5彩色照片和35mm彩色幻灯片。这些照片中每个印章的实际尺寸打印在卡片上，并由艺术家和收藏家分类。并对各印文的真伪和年代进行了考察。为了更准确地确定印章的年代和年代，有必要在三年研究的基础上，对印章进行更大规模的编纂。有鉴于此，本研究将研究资料进行分类整理，并以计算机记录。

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.
