When the design is finished, it will be printed. The finished product of printing is inseparable from the selection of paper. It is very important to understand the basic knowledge of printing paper.

全紙張

All paper

平板紙出廠時被裁切成一定的尺寸，供大幅面單張紙印刷機使用，這叫「全張」，全張也可被印刷廠進一步分切成較小的幅面用于各種型號的單張紙印刷機。

Flat paper is cut into a certain size when it leaves the factory for large format sheet fed printing machines. This is called "full sheet". Full sheet can also be further cut into smaller format for various types of sheet fed printing machines.

全張的面積是整個造紙業(yè)和印刷業(yè)一致采用的特定規(guī)格。在我國，使用多的是這幾種規(guī)格，它們都有約定俗成的名稱：

The area of the sheet is a specific specification adopted by the whole paper industry and printing industry. In China, these specifications are most commonly used, and they all have conventional names

紙張開本

Paper format

按標準規(guī)定生產的紙張稱作全開紙，把一張全開紙裁切成面積相等的若干小張，叫多少開數。如全張紙被分為兩半，每一半稱為「對開」，全張紙被分成 4 份，每一份稱為「4開」。如我們熟悉的「16開」就是全開紙分成了16份。

The paper produced according to the national standard is called full open paper. A sheet of full open paper is cut into several small sheets with equal area, which is called the number of open sheets. If the whole sheet is divided into two parts, each half is called "folio", and the whole sheet is divided into four parts, each part is called "folio". As we are familiar with the "16 open" is full open paper divided into 16 parts.

紙的定量

Quantitative analysis of paper

紙張「定量」即每紙的重量，以克為單位。定量的真正意圖并不是給紙張稱重，而是反映紙張的厚度。定量愈高，紙張愈厚。

Paper "ration" is the weight of paper per square meter, in grams. The real intention of quantification is not to weigh the paper, but to reflect the thickness of the paper. The higher the ration, the thicker the paper.

比如某種銅版紙每的重量是 157 克，它就被稱為「157 克銅版紙」。

For example, a certain coated paper weighs 157 grams per square meter, which is called "157 grams coated paper".

常用紙張類型

Common paper types

1. 銅版紙

1. Coated paper

銅版紙是彩色印刷常用的紙張，表面光滑、潔白度高、吸墨著墨性能好，主要用于畫冊、書刊、DM、海報等。銅版紙還分有光和無光兩種，俗稱「光銅」和「啞粉」。光銅印刷顏色鮮艷，色彩還原性好，啞粉印刷顏色厚重，顯得更高檔。常用的定量有 128 克、157 克、200 克、250 克、300克。

Coated paper is the most commonly used paper for color printing, with smooth surface, high whiteness and good ink absorption and inking performance. It is mainly used for picture books, books, DM, posters, etc. There are two kinds of coated paper, light and matte, commonly known as "light copper" and "matte". Bright copper printing color, color reduction is good, dumb powder printing color thick, appears to be more high-grade. The commonly used quantitative methods are 128 g, 157 g, 200 g, 250 g and 300 G.

2. 膠版紙

2. Offset paper

膠版紙是消耗量大的印刷用紙，彩色印刷效果比銅版紙差一些，多用于對顏色要求不高的黑白書刊、教科書等。紙張較薄，定量一般在 60 克 120 克之間。

Offset paper is the largest consumption of printing paper, color printing effect is worse than coated paper, more used in black and white books, textbooks, etc. The paper is thin, and the ration is generally between 60g and 120g.

3. 白卡紙

3. White cardboard

韌性與硬度高，不易斷裂，很像厚的銅版紙，但區(qū)別是白卡紙的表面沒有無機涂料，吸墨性比銅版紙強，但印刷的顏色不是那么鮮艷。紙張較厚，常用定量有 200 克、220 克、250 克、270 克、300 克、400 克。常用于名片、請柬、明信片、包裝等。

High toughness and hardness, not easy to break, much like thick coated paper, but the difference is that there is no inorganic coating on the surface of white cardboard, ink absorption is stronger than coated paper, but the printing color is not so bright. Thick paper, commonly used quantitative 200 g, 220 g, 250 g, 270 g, 300 g, 400 G. Commonly used in business cards, invitation cards, postcards, packaging, etc.

4. 牛皮紙

4. Kraft paper

紙面呈黃褐色，質地堅韌，但顏色不勻，表面粗糙（在某些情況下這恰恰是所需要的效果）。廣泛應用于食品包裝、檔案袋、信封等，也用來做體現(xiàn)古樸文化的書籍封面和宣傳單。

The paper is yellowish brown and tough, but uneven in color and rough in surface (which is exactly the effect required in some cases). It is widely used in food packaging, file bags, envelopes, etc. it is also used to make book covers and flyers reflecting ancient culture.

5. 硫酸紙

5. Sulfuric acid paper

原紙經硫酸處理后變得半透明，印刷時可以簡約地印一些文字或圖案。它常用于高檔書籍、畫冊的襯紙，能夠透過它看見扉頁上的圖文。定量有 75 克、60 克、45 克。

The base paper becomes translucent after sulfuric acid treatment, and some words or patterns can be printed simply. It is often used as the backing paper of high-grade books and picture books, through which you can see the pictures and texts on the title page. There are 75g, 60g and 45g in the ration.

6. 特種紙

6. Special paper

特種紙也叫花式紙，由不同材質的材料制成，是各種特殊用途紙或藝術紙的統(tǒng)稱，種類繁多，或有紋理，或有特殊的質感。但相對高于普通紙張，多用于時尚前衛(wèi)的包裝、吊牌、書籍封面、名片等，運用得好可讓印刷品別具一格

Special paper, also known as fancy paper, is made of different materials. It is a general term for all kinds of special purpose paper or art paper. There are many kinds of paper, either with texture or special texture. But the price is relatively higher than that of ordinary paper. It is mostly used for fashionable and avant-garde packaging, hangtag, book cover, business card and so on. Good use can make the printed matter unique
