2. Conservation Process
1) Preliminary research
(1) Size, depth, and damages were recorded with photo evidence.
(2) Forms of pigment surfaces were examined by magnifying the analyzed areas by a video
microscope (IMS-M-345, Sometech Vision)
(3) A portable X-ray Fluorescence Analyzer(Oxford Z-MET 5100) was used to identify the
qualitative and quantitative composition of the pigments.
2) Dry cleaning
The surface was cleaned by Dry sponge eraser.

4) Wet cleaning
The painting was cleaned by spraying of filtered fresh water
wet cleaning
Contaminants absorbed onto the cleaning paper
5) Removing the backing paper
(1) Sewn threads were removed prior to removing backing papers
(2) The patterned papers decorating along the edges of the scroll were pasted on
the top of the mounting, even on the links of mounting papers. Thus, the backing
papers were removed without separating mounting and painting.
