What ink does Syaraku 14k Ye Wan use? Why is the rice paper not smooth?

Syaraku 14k Wanye can use black ink, cyan ink and Syaraku cyan ink. The unsmooth rice paper should be due to the mismatch between the book and the paper.

Xuan paper is divided into raw Xuan and cooked Xuan according to its water absorption performance. Shengxuan is ordinary rice paper, which has not been processed. Because there are a lot of wrinkles on the cell wall of phloem fiber of raw material Pteroceltis tatarinowii, it can contain some small particles, which is helpful to absorb ink. Therefore, writing in Sheng Xuan style will be degraded, and because of its characteristics, it is mostly used for freehand brushwork or cursive writing, which is not conducive to writing in middle letters, especially in lower letters. Brush a layer of alum water on raw rice paper to make it lose its aging and obvious water absorption, and the raw rice paper becomes mature rice paper, especially suitable for regular script, official script, seal script and meticulous painting.
