Analysis of light paper
Author:
It is not difficult for people who often visit bookstores to find that more and more medium and high-end books and periodicals begin to use a kind of paper with light texture, soft and natural color, and good printing quality. This new type of printing paper is called "light paper" or "Munken paper", which is gradually favored by printing plants and readers, and is widely used. Many users and readers are still unfamiliar with light paper. This article will introduce the origin, production process characteristics and printing suitability of light paper from the perspective of paper manufacturers, so that everyone can have a deeper understanding of light paper.

Origin of the name "light paper"
This kind of special printing paper has been given many titles, such as light paper, light paper and Muncan paper. This kind of paper was first produced by the Munkendal paper mill in Sweden in the 1970s. It was named Munkendal locally. In 1997, Polo Co. of Austria entrusted China Printing Materials Corporation to distribute it in China for the first time. When it was introduced to China, it had the name "Munkendal". According to the company, it is a kind of loose thick offset paper. At first, it was called "Monken light offset paper", or "Monken paper" for short. Later, some people called it "light printing paper" or "light paper", "light printing paper", etc. In fact, according to its English name "Light Weight Printing Paper", it should be translated into "light printing paper". As it is the first light offset paper introduced in China, it is now habitually called "Monken paper" or "light paper" in China.
Compared with ordinary offset paper, light paper is characterized by its high loose thickness. The loose thickness is an index reflecting the paper density. Expressed by the ratio of paper volume to weight, the loose thickness of ordinary offset paper is about 1.2cm3/g, while the loose thickness of light paper is 1.3~2.15cm3/g (there are 1.3, 1.5, 1.8, 2.0, 2.15 and other grades). At present, the loose thickness of light paper used in the domestic market is generally about 1.8cm3/g. In the printing of books and periodicals, light paper with low quantity can replace offset paper with high quantity, which can reduce the cost on the basis of ensuring the printing quality and the thickness of printed matter. At the same time, due to the low quantity of the paper, the book is relatively light, and has been welcomed by the publishing industry. In economically developed countries such as Europe, America and Japan, more than 95% of books have been printed on light paper.
