Wuxi Zhongjiang Color Printing tells you how to set it to bleed to be correct

In the album printing process, the bleeding we often say is the printing term 'bleeding position', also known as 'acupoint'. Its role is mainly to protect the colored areas from unintentional when the finished product is cut, so that the colors completely cover the places to be expressed. For example: If you want a solid circle printed on white paper, everyone cut it with scissors. If you cut it according to the edge of the circle, no matter how seriously, you will shed a little more or less black paper, The black circle cut out in this way has a little white border, and no matter whether it is round or not, as long as the white border left on the black circle makes people feel uncomfortable.
Is there any way to ensure that the circle cut out by anyone will not have white borders? In fact, it is very simple. When making this solid circle, the boundary of color is slightly overflowed, that is, enlarged. This adds an extra point of insurance without leaving white edges. In actual picture book printing, the circles in the example may be packaging expanded graphics of various shapes, and the black in the example will also be other colors. Is there any quick and uniform way? Of course, the standard size of the bleeding site currently implemented is 3mm. It is the side that is increased by 3mm along the actual size. This 'edge' is appropriate for the natural expansion of color within the size.
The uniformity of the bleeding position to 3MM has several advantages: 1. It is the manuscript that is produced, and the designer does not need to go to the printing house to tell them how to cut (of course, the actual shape is accurately judged by the cutting mark in the manuscript) 2. It is the size of the paper used when printing in a printing plant.
Usually we need to pay attention to the bleed line after the design is completed when making the design file of the book printing. How to set the bleed is mainly considered the binding method and the layout method after printing. General product samples use saddle stitching. For a single page, the bleeding is on three sides, and the bleeding directions on the left and right pages are different. Therefore, bleeding should be added when setting the page. Generally, when designing a facing page, add 3mm to the top, bottom, left, and right of the page, not to the middle. The same is true for thicker books and magazines such as the use of lock-line stitching. If you use paperback proofreading for a single page, it is bleeding on all sides, but it is more difficult to deal with bleeding on all sides with a cross-page pattern in the middle, so generally no bleeding is set.
When manually making a layout, the pages must first be split into single-page files, which are generally packaged into EPS files (PDF files can also be used). There is no bleeding when packing on three sides of the bleeding; you can add bleeding settings when packing on all sides. The single-page file generated at this time will naturally remove the part outside the page or the bleeding, and the pattern text of the cross-page will be automatically separated.
