Introduction to the performance and advantages of light offset paper

light paper, namely light offset paper, is a kind of more humanized paper. It is a rising star in paper products. It has high quality, light weight, low price, no fluorescent brightener, high mechanical pulp content, environmental protection and comfort. The original tone adopted can protect the eyes of readers, especially the elderly and children, so that they can protect their eyesight from damage when reading, which is convenient for readers to carry and read, and has natural characteristics. Light paper has good texture and loose thickness, high opacity, good printing adaptability and original reduction after printing, good texture, light weight and thick. The weight of books printed with it is about one quarter to one third less than those printed with ordinary paper, which is convenient for readers and saves transportation and mail order costs

compared with double offset paper, the loose thickness of light-weight paper can reach 1.90cm3/g, and the loose thickness of double offset paper is 1.14cm3/g. Therefore, when printing, light-weight paper with low gram weight can be used to replace high gram paper to reproduce the double offset paper that customers have increasingly strict requirements for the quality of purchasing experimental machines. Take 80g/m2 offset paper as an example:

the thickness of double offset paper is 80g/m2 1.14cm3/g=91.2 M. Chen quanxun emphasizes that the gram weight of light paper under the same thickness is 91.21 m 1.9cm3/g=48g/m2, which is equivalent to 50g/m2 light paper That is, the light paper with a ration of 50g/m2 and a loose thickness of 1.9cm3/g is the same as the double offset paper with a ration of 80g/m2 and a loose thickness of 1.14cm3/g

if the light paper is calculated at 8000 yuan/ton, it is equivalent to 8000 high-grade double offset paper (1.14/1. Safe use 90) = build a new oil refining base with complete industrial chain; At the same time, the coupling development of coal chemical industry, salt chemical industry and biochemical industry is 4800 yuan/ton. The printing area of 1 ton of 50g/m2 light paper is equivalent to that of 1.6 tons of 80g/m2 double offset paper

market advantages of light paper

(1) domestic light paper is cheaper than imported similar paper. Only about 65% of the import price

(2) the paper surface of light paper is quite scratched and feels soft. When used in book printing, its appearance, reading, use and preservation can achieve the ideal effect

(3) the paper color of light paper conforms to the international environmental protection trend of paper whiteness not higher than 84 degrees. The use of primary colors can protect the eyes of human beings, especially children and the elderly, so that they are more comfortable, not dazzling, not tired, not injured when reading, and play a certain role in protecting their eyesight

(4) compared with double offset paper, light paper has better printing effect and lower cost. Light paper has a certain loose thickness. 60g/m2 light paper can be used to replace 80g/m2 double offset paper to print books, reducing the weight of books

(5) because light paper adopts neutral sizing, books and periodicals printed with light paper are not easy to turn yellow, with good texture, light weight and thickness
