更常见的书刊画册印刷的就是双铜纸。这种纸张的克重有80g、105 g、128 g、157 g、200 g，250 g，300 g和350 g。那么，克重怎么选择呢？
The most common picture book is printed on double copper paper. The weight of the paper is 80g, 105g, 128G, 157G, 200g, 250g, 300g and 350g. So, how to choose g Chong?
一般来说，画册的封面用纸以300 g为多。内页大部分可以随着页数的增加而减少。例如16页以下的画册，内页可以用200 g双铜纸或者再重一点，这 样的画册避免给人小气、单薄的感觉。 20页至40页之间的画册，内页可以用157 g双铜纸。如果印刷页数在40页以上，内页用128 g的双铜纸也可 以。
Generally speaking, the cover of the album uses more than 300 g of paper. Most of the inner pages can be reduced as the number of pages increases. For example, for a picture album with less than 16 pages, the inner page can be made of 200 g double copper paper or a little heavier. Such a picture album can avoid the feeling of stinginess and thinness. For the album between 20 and 40 pages, 157 g double copper paper can be used for the inner page. If the number of printed pages is more than 40, 128 g double copper paper can also be used for the inner page.
当然前面所说的克重设计也要考虑书刊画册的印刷成本。假如画册的页数很多，有时上百页甚至几百页时，更好选择封面采用200 g双铜纸，内页就用80 g双铜也行。
Of course, the above-mentioned weight design should also consider the printing cost of books, magazines and picture books. If the album has many pages, sometimes hundreds or even hundreds of pages, it's better to choose 200 g double copper paper for the cover and 80 g double copper for the inner page.
There is also a commonly used paper called matte paper. In addition to the matte paper, other weight and price aspects are completely consistent with the double copper paper. As far as the effect is concerned, these two kinds of paper have better effect on the reduction of printing color.
In addition, book paper is also a kind of common paper. It is generally used to print picture books with more words, and the most commonly used one is books, periodicals or magazines. But its color reduction effect is much worse than that of copper paper or matte paper.
With the increasingly fierce market competition, many enterprises use high-end paper printing for the needs of brand image or high-end customers, which is very much in the auction house or the first edition of professional album in recent years
For example, the biggest advantage of super sensitive paper is that there is a layer of so-called cloth on the surface of the paper, where there is no printing, it presents a sub color, while where there is printing, it presents a bright color. Therefore, it has become the first choice for many high-end books, magazines and picture books printing.
There are also some art paper, which is more suitable for art album printing and some special design effect albums.
