Choose the paper for book printing in china need to consider the positioning, cost, category and other factors of the book.In the last article, we introduced in detail the factors that need to be considered when selecting paper. Today, let's briefly introduce how to select the inner page of books. 

China book printing,the inner page paper of book body: generally use coated paper, offset paper or light paper. 

1.The advantage of coated paper: a layer of white slurry is coated on the base paper, and the paper made by calendering has a smooth surface, high whiteness, uniform distribution of paper fibers, uniform thickness, small flexibility, good elasticity,with strong water resistance and tensile properties, the absorption and reception of ink are very good.

Coated paper is mainly used for albums printing ,bulk calendar printing, postcard printing ,etc. 

2.The advantage of offset paper: offset paper has small flexibility, uniform ink absorption, good smoothness, tight and opaque texture, good whiteness and strong water resistance.

Offset paper suitable for printing single or multi-color book covers, text, inserts, pictorials, maps, publicity albums, etc. 

3.The advantage of light paper: light paper is a rookie in paper products. It does not contain fluorescent whitening agents, and is mostly milky white, beige, and valley white. The color is soft and has a certain protective effect on vision. At the same time, the lightweight paper has good texture and bulk, folding resistance, high opacity, good printing adaptability and good restoration of originals after printing.

Most importantly, the weight of this paper is relatively light, The weight of the books printed with it is about one-quarter to one-third less than that of the books printed with ordinary paper, which is convenient for readers to read and saves shipping cost. 

In short, the coated paper is smooth and reflective. Generally, coated paper is used for coloring book printing,such as color magazines,beauty books, and full-color multi-picture books. Offset paper is mostly used for black and white printing, full-color and two-color books with few pictures will also use offset paper. Coated paper of the same gram weight is more expensive than offset paper, which means coated paper is more expensive than offset printing for the same book. 

As for the paper of selection criteria, it depends on what type of book is published. Choose according to your needs, expensive is not necessarily better. Although the coated paper has a smooth surface and high color rendering performance, it is suitable for displaying a large number of pictures, but if it is biased towards books with more text, the use of copper plate printing will not only increase the cost, but also indirectly increase the price. It will also cause visual fatigue under long-term reading. Therefore, books with a lot of text generally use offset printing. 

In addition, for the same gram of paper, the copper plate is much thinner than the offset plate.Which has a problem,for two books of the same price, the thicker one will make people feel more affordable, and some books themselves do not have many pages, if use thinner paper , it will result in insufficient thickness. 

Thickness comparison of coated paper and offset paper. Even if you decide whether a book printing china needs a copper plate or an offset plate, you also need to consider the thickness of the paper. The paper is more lighter, it will more thinner and cheaper. If you use too thin paper, the worst case, the words on the back will show through, and the light paper will be easily damaged and ink smeared.

However, it is also necessary to choose the appropriate thickness and weight according to the application scenario and other factors. For example, a casual story book printing, the content is relatively easy, then the book is designed to be light, thin and portable, which is very friendly to readers, so you can choose light paper. If for the high end hardcover book printing, choosing thicker and heavier paper will increase the value and weight of the book, and naturally thicker paper is better. 

  In addition to thickness and weight, the whiteness of the paper is also an important parameter. Books with full text generally use slightly yellower paper, which is not easy to cause visual fatigue. If it involves two-color, four-color (full-color) printing, even if you use offset paper, you must choose paper with high whiteness, because the color rendering effect will be better. The paper itself is yellow, and the ink cast will be very strong. 

  In short,choosing the inner paper for your book,which depends on what type of book you want to print,expensive is not necessarily better,suitable is the most important.
