A: Generally, the common sheet of paper is called No. 0 paper. The paper is divided into large and positive degrees. The so-called opening number is the number of equal parts of the No. 0 paper. For example, the 16 equal parts are 16K. Taking the degree 16 as an example, the net size is 210mm×285mm, and the bleeding edge (each 3mm on each side) needs to be set in the PS, that is, the actual image size is 216mm×291mm. The simplest way of other normal opening numbers is to multiply the length and width of 16K by the corresponding multiple, for example 4K is the multiplication of 2 on each side. That is 210mmX2 = 420mm, 285mmX2 = 570mm (net size), and then add the width of the bleeding edge on it. It should be noted that the above is the most basic method of opening. There are many ways to open paper. There is no one to describe here. You can browse the corresponding printing websites by yourself to understand the different methods of opening and opening the paper.
