Wuxi Zhongjiang color printing tells you how to set the correct bleeding

In the printing process of the picture album, we often say that bleeding is the printing term 'bleeding position', also known as' point out '. Its main function is to protect the finished product cutting, where there is color, in the case of unintentional, to make the color completely cover the place to be expressed. For example: if you want a solid circle printed on white paper, you can use scissors to cut it. If you cut it according to the edge of the circle, no matter how serious you are, you will more or less flow a little white paper without black printing. The black circle thus cut has a little white edge, and no matter it is not round, as long as the white edge left on the black circle is not too comfortable 。

Is there any way to make sure that no one cuts out a circle with a white edge? In fact, it's very simple. When you make this solid circle, you will overflow the color line a little, that is to say, increase it. In this way, it will not leave a white edge to increase the insurance. In the actual album printing, the circle in the example may be a package of various shapes, and the black in the example may also be other colors. What is the fast and unified way? Of course, now the standard size of the bleeding position is 3mm. It is an edge increased by 3mm along the actual size. This' edge 'is suitable for natural enlargement of color in size.

There are several advantages to unify the bleeding position into 3mm: 1. It is the manuscripts produced without the designer going to the printing factory to tell them how to cut (of course, to accurately judge the actual shape is according to the cutting mark in the manuscripts); 2. It is to use the paper size when the printing factory is making up the plate printing.

Generally, we need to pay attention to the bleeding line after the completion of the design when making the design documents for album printing. How to set the bleeding is mainly to consider the binding mode after printing and the way of large plate collage. General product samples use horse riding order. For a single page, there are three sides of bleeding, and the bleeding direction of the left and right pages is different, so you should add bleeding when setting the page. In general, 3mm is added to the top, bottom, left and right of the opposite page respectively, but not in the middle. For thicker books and magazines, such as the use of lockstitch is the same. If we use the paperback to revise the single page, it is difficult to deal with the bleeding on four sides, but considering that there is a cross page pattern in the middle, so generally there is no bleeding.

When assembling a large version manually, the page should be divided into a single page file, which is usually packaged into EPS file (PDF file is also available). No bleeding is needed in packing of three-sided bleeding, and bleeding setting is needed in packing of four-sided bleeding. At this time, the generated single page file will naturally remove the parts outside the page or bleeding, and automatically separate the cross page pattern text.
