Although the designs and wording of the two prints are almost identical, the lines are entirely different. The finesse of the London Print in intaglio is discernible in the lines of the water wave in the Carp stamps and of the cloud wave in the Flying Goose stamps which look more distinct than in the lithographed stamps. The marked difference is the change of the English wording into 〝Chinese Imperial Post.〞　　The watermarked paper used for stamp printing in London was supplied by the Customs Statistical Department, Shanghai; but after the supply had been exhausted, the stamps were printed on unwatermarked paper, the designs and plates remaining unchanged.　　At the beginning of the printing, the unwatermarked stamps were the same as watermarked ones both in face value and color, the only exception being that the former had an extra denomination of 5￠in orange. However, in conformity to the provisions of the Universal Postal Convention and in coping with business requirements, the following new stamps were printed with some change in color：(1) 2￠ stamp (green) and 10￠ stamp (blue) issued in 1.1.1909 (34th year of Emperor Kuang Hsu)(2) 4￠ stamp (vermilion red) issued in 1.1.1910 (1st year of Emperor Hsuan Tung)(3) 3￠ stamp and 7￠ stamp issued in 3.1910(2nd year of Emperor Hsuan Tung.)
