However, for Xuan paper, there are also some shortcomings. One is the high cost. At present, the real price of rice paper is rising because of the increase in labor costs. Generally only calligraphy and painting are used. If the rice paper used to print genealogy is not real rice paper. Due to the lightness and softness of rice paper, the current generation of bookbinding machines can not be mass-produced smoothly, and more are semi-manual bookbinding. In particular, thin rice paper can not be printed on both sides, which will further increase the cost of genealogy.
With the improvement of rice paper technology, the thickness of rice paper produced in China has increased, which can basically meet the printing requirements of modern printing machines, and can also be printed on both sides to reduce costs. Genealogy is generally standardized and unified in this design by the printing unit of ancient books, but there are also a few existing new genealogies designed like non-images in this respect. Some even don't print the plate mouth or the plate heart to save trouble, which makes the content difficult to find and the arrangement chaotic. Some pages are inconsistent with the pages in the text, which is not serious. Secondly, the camphor boxes stored in camphor boxes generally have the function of moisture-proof and insect-proof, and the genealogy will not be eaten by insects for a long time, which is helpful for the preservation of genealogy.
