General study of signature and seals of Chinese painters, calligraphers and collectors in Japanese collection and making the research materials into database

我们对日本收藏的中国书画作品的艺术家和收藏家的签名和印章进行了研究。首先，我们用6×4.5大小的相机拍摄艺术家和收藏家的签名和印记的实际大小的黑白照片，并粘贴在数据卡上进行分类。这些照片与之前拍摄的照片一起，也被用扫描仪作为数据库制作成数字图像。太大而无法拍摄实际大小照片的印记是用数码相机拍摄的。我们讨论了材料数据库与数字图像；什么方法是最有效的利用签名和印章的实际尺寸的照片。我们需要进一步讨论这件事。我们编写了一份报告，展示了未来出版中国书画作品艺术家和收藏家签名和印章的基本格式。

We carried out a research on signatures and seals of the artists and collectors on Chinese paintings and calligraphic works in Japanese collections. First, we took actual size black and white photographs of the signatures and seal marks of the artists and collectors with 6×4.5size camera and were pasted on data cards for sorting. The photographs, together with those taken previously, were also made into digital images using a scanner for database. Seal marks too large to take actual size photographs were photographed with a digital camera. We discussed database of the materials with digital images; what method is most effective for the utilization of the actual size photographs of the signatures and seals. We need to further discuss this mater. We compiled a report which shows the basic format for the future publication of Signatures and Seals of the Artists and Collectors on Chinese Paintings and Calligraphic Works.
