印刷纸张的咬口位问题

来源:http://www.xinfengyinshua.cn/   发布时间:2021-02-22
咬口是印品的前端,又叫牙口,是印刷机叼纸时的位置,而且我们一般在印刷东西时,看到印刷的尺寸,就会着手拼版工作,而拼版的时候,通常就会存在纸张的咬口位问题,下面,就带大家来了解一下印刷纸张的咬口位问题。
Bite is the front end of the print, also known as the mouth, is the position of the printing machine when holding the paper, and we generally print things, see the size of the printing, we will start to make up, and when making up, there is usually a problem of the bite position of the paper. Now, let's take you to understand the bite position of the printing paper.
咬口是指印刷机械在传送纸张的时候,纸张被印刷机械送纸装置所夹住的那部份位置,此处是印刷油墨无法着色的部分,在设计版面或拼版时,不能有画面内容。无论是对开、4开或8开机印刷,在输送纸时有一边是咬口。
Bite refers to the position where the paper is clamped by the paper feeding device of the printing machine when the printing machine is conveying the paper. This is the part that cannot be colored by the printing ink, and there can be no picture content when designing the layout or making up. Whether it is split, 4 or 8, there is a bite on one side when conveying paper.
咬口是指在承印过程中首先被传送进机器的一边,也是印版碰不到的部位。一般控制在7毫米至15毫米之间,所以计算实际印刷面积时需要扣除咬口部份的非印刷面积。
Bite refers to the side that is first transferred into the machine in the process of printing, which is also the part that the printing plate cannot touch. Generally, it is controlled between 7mm and 15mm, so the non printing area of the undercut should be deducted when calculating the actual printing area.
自翻版,是在一个印张中,一半印正面图文,另一半印反面图文,正反面用同样的印版各印一次,成为两从印刷品。印刷中,可以节省印工和PS版。按版面排布形式,又分为上下自翻版和左右自翻板。拼版时要注意左右版留一个咬口位,而上下版要留两个咬口位。
Self copying is a process in which one half of a sheet is printed on the front side and the other half on the back side. The front and back sides are printed on the same plate once each to form two subordinate prints. In printing, you can save printer and PS plate. According to the layout form, it can be divided into up and down self flipping and left and right self flipping. Make up should pay attention to the left and right version to leave a bite, and the upper and lower version to leave two bite.
总而言之,咬口作为印刷机器在传送纸张时,纸张被印刷机送纸装置夹住的位置,在印刷机中油墨是印不到的,所以在实际印刷面积中需要扣除咬口部份。
In a word, as the position where the paper is clamped by the paper feeding device of the printing machine when the printing machine is conveying the paper, the ink cannot be printed in the printing machine, so the bite part needs to be deducted from the actual printing area.
