Shodo Daisuki Episode 26 – Video Overview

This video features an explanation by Shimauchi on the backing (urauchi) process in calligraphy.
Backing is a technique in which paper is applied to the back of a finished work to prevent wrinkles and sagging, reinforce the piece, and provide insect protection.
Shimauchi explains that backing is one of the most popular experiences in calligraphy workshops.

The video introduces two main methods: machine backing and hand backing.
Shimauchi explains that due to the nature of paper, areas where ink is applied shrink, while areas without ink do not, resulting in distortion and wrinkles in the artwork.
Therefore, backing is essential to bring the piece into a condition suitable for appreciation.

In the machine backing process, the condition of the artwork is first checked to determine whether bleed prevention is necessary.
The piece is then placed face-down, misted with water, stretched by hand, and run through a press for preliminary stretching.
Next, heat-reactive adhesive backing paper is cut slightly larger than the artwork and placed adhesive-side up.
Care must be taken to prevent dust from entering at this stage.
After lightly pressing with an iron using protective paper, the work is pressed again to complete the backing.
Finally, the piece is trimmed in a finishing cut (“keshō-dachi”) to complete the process.

For the hand backing demonstration, Shimauchi uses a single-character work reading “Tanoshii” (Fun) that he personally wrote.
He introduces the tools used: laundry starch, a professional brush, a fine mist spray bottle, and backing paper (Shiratori paper for mounting).
In the demonstration, the artwork is turned over, misted, stretched, and then bonded with adhesive-coated backing paper, pressing out air with a brush.
Finally, glue is applied to the edges, and the piece is mounted on a panel to dry.
Shimauchi explains that backing completely removes wrinkles and sagging, and that the white backing paper enhances the depth and clarity of the black ink.
He also introduces iron-on backing paper as an alternative for those who find traditional backing difficult.
