The standard size of 8K paper is 420mm × 297mm, the size of the paper layout is called the format, and the format is calculated in full sheet paper.
When many people go to buy paper, they often see 8k paper this specification of paper, they do not know how big 8k paper is, let’s understand it together.
Details
01
The specification of paper refers to the paper made, trimmed and trimmed to a certain size. In the past is how much “open” (such as 8 open or 16 open etc) to express the size of paper, now our country adopts the international standard, the regulation A0, A1, A2, B1, B2…… To indicate the size of the paper. The standard states that the ratio of width (represented by X) to length (represented by Y) of paper is X: Y=1: n.
02
The naming of my country’s habit of opening the book is named after the geometric level. 32 open, then folded to 64, push in order.
03
The current formats of books and periodicals in my country are mainly A series specifications, which are as follows: A4 (16k) 297mm×210mm; A5 (32k) 210mm×148mm; A6 (64k) 144mm×105mm; A3 (8k) is generally used 420mm×297mm. A2 (4k) 420mm×594mm.
04
Due to the popular development of A4 paper, 16K paper is slowly fading out of the market. Hospitals use medical records for about A4, but because of the need to print images for doctors to view and record in the medical record when examining an organ, if you use A4 inkjet paper, then the printed images are not well stored in the A4 medical record, so hospitals print the images of the examination using 16K paper.
05
6 The size of the open paper is 185mm*260mm. 16-sheet paper is rarely used in hospitals, because the amount of paper required for writing medical records in hospitals is also quite large, and 16-sheet paper is more expensive than B5, so B5 is widely used in hospitals now.
