全纸张
Full paper
平板纸出厂时被裁切成一定的尺寸，供大幅面单张纸印刷机使用，这叫「全张」，全张也可被印刷厂进一步分切成较小的幅面用于各种型号的单张纸印刷机。
Flat paper is cut to a certain size when leaving the factory for use by large format sheet fed printers, which is called "full sheet". The full sheet can also be further cut into smaller format by the printing factory for various types of sheet fed printers.
全张的面积是整个造纸业和印刷业一致采用的特定规格。在我国，使用多的是这几种规格，它们都有约定俗成的名称：
The area of the full sheet is a specific specification adopted by the whole paper industry and printing industry. In China, these specifications are used most, and they all have conventional names:
纸张开本
Paper format
按标准规定生产的纸张称作全开纸，把一张全开纸裁切成面积相等的若干小张，叫多少开数。如全张纸被分为两半，每一半称为「对开」，全张纸被分成 4 份，每一份称为「4开」。如我们熟悉的「16开」就是全开纸分成了16份。
The paper produced according to the national standards is called full open paper. Cut a full open paper into several small sheets with equal area, which is called the number of openings. If the whole sheet of paper is divided into two parts, each half is called "open", and the whole sheet of paper is divided into four parts, each part is called "4 open". As we are familiar with "16 open" is that the full open paper is divided into 16 parts.

纸的定量
Quantitative of paper
纸张「定量」即每纸的重量，以克为单位。定量的真正意图并不是给纸张称重，而是反映纸张的厚度。定量愈高，纸张愈厚。
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 weight, the thicker the paper.
比如某种铜版纸每的重量是 157 克，它就被称为「157 克铜版纸」。
For example, a kind of coated paper weighs 157 grams per square meter, which is called "157 grams of coated paper".
常用纸张类型
Common paper types
铜版纸
art paper
铜版纸是彩色印刷常用的纸张，表面光滑、洁白度高、吸墨着墨性能好，主要用于画册、书刊、DM、海报等。

The commonly used quantities are 128 g, 157 g, 200 g, 250 g and 300 G.
胶版纸

胶版纸是消耗量的印刷用纸，彩色印刷效果比铜版纸差一些，多用于对颜色要求不高的黑白书刊、教科书等。纸张较薄，定量一般在 60 克 120 克之间。
Offset paper is the most consumed printing paper. The color printing effect is worse than coated paper. It is mostly used in black-and-white books and textbooks with low color requirements. The paper is thin, and the weight is generally between 60g and 120g.
白卡纸
White cardboard
韧性与硬度高，不易断裂，很像厚的铜版纸，但区别是白卡纸的表面没有无机涂料，吸墨性比铜版纸强，但印刷的颜色不是那么鲜艳。纸张较厚，常用定量有 200 克、220 克、250 克、270 克、300 克、400 克。常用于名片、请柬、明信片、包装等。

The paper is thick, and the commonly used quantities are 200g, 220g, 250g, 270g, 300g and 400g. Commonly used in business cards, invitations, postcards, packaging, etc.
牛皮纸
Kraft paper
