Positive paper (787mm 1092mm) is the standard of domestic paper size, and large paper (889mm 1194mm) is international standard paper.

Paper has international standards and domestic standards, that is, the international standard is called large paper and called class A paper, and the domestic standard is called positive paper and class B paper (different from the B group paper specified in the international standard ISO 216), in the actual paper printing production work, the type of paper used will be selected according to the different requirements of each customer, and the paper is cut and cut.

Precautions for the use of generous paper.

Large folio paper (large 2 open) in the cutting, the size after the trimming size must be 570 860mm, strictly speaking, it can be a little larger or smaller, on the premise of trying not to waste paper, theoretically the bigger the better, but because it is necessary to take into account the size of various printing presses.

It is also necessary to consider the use of various scenes, and finally everyone agreed that it is just right to cut it to 570 860mm, and it is an integer and easy to remember, and it saves costs as much as possible. The same is true for the size of other finished products, and we can directly apply the size of the finished product when designing the work.

Positive paper: 787 1092mm, large paper: 850 1168mm.

Number of openings (positive) size units (mm): full opening 781 1086, folio 530 760, 3 open 362 781, 4 open 390 543, 6 open 362 390, 8 open 271 390, 16 open 195 271.

Positive and generous both refer to the size of the paper, in order to adapt to the requirements of different prints, the paper is divided into 2 specifications, taking the whole sheet paper as an example, the size of the full open is 787 * 1092mm, the size of the full open paper is 889 * 1194mm, all the specific sizes can refer to the paper opening table.
