We often say that bleeding is the printed term 'bleeding position', also known as' out point '. Its role is mainly to protect the finished product cutting, the color of the place is not intentional, so that the color is completely covered to the place to be expressed. For example, if you want a solid circle printed on white paper, we cut with scissors, if you cut the edge of the circle, no matter how serious, it will more or less flow down a little black white paper, so that the black circle with a little white edge, and no matter whether the cut is round or not, as long as the white edge left on the black circle will make people feel not too comfortable. Is there any way to ensure that no one cuts out a circle with a white edge? In fact, it is very simple, that is, when making this solid circle, the color line is slightly overflow, that is, increase. This adds an extra layer of insurance against leaving a white edge. In practice, the circle in the example might be a package expansion graph of various shapes, and the black in the example would be other colors. What's a quick and uniform way to do this? Of course, the standard size of the bleeding site is now implemented: 3mm. It is an edge increased by 3mm along the actual size. This "edge" is ideal for the natural expansion of color within the size. The bleeding position is unified to 3MM has several advantages: 1. It is the manuscript that is produced, and the designer does not have to go to the printing house to tell them how to cut (of course, the most accurate judgment of the actual shape is according to the cutting mark in the manuscript); 2. It is the maximum use of paper size when printing in the printing plant.
Usually, we need to pay attention to the bleeding line after the completion of the design, and how to set the bleeding is mainly to consider the binding method and the way of spelling large plates after printing. General product samples use riding set, for a single page is bleeding on three sides, and the bleeding direction of the left and right pages is different, so the page should be set up with bleeding. Generally, when the page design is used, 3mm is added to the top and bottom of the page, and the middle is not added. The same is true for thicker books and magazines such as the use of lock lines. If the paperback revision is four-sided bleeding for a single page, but considering that there is a cross-page pattern in the middle, four-sided bleeding is more difficult to deal with, so there is generally no bleeding. When manually spelling a large version, the page must first be split into a single page file, generally packaged into EPS files (PDF files can also be used). Three sides bleeding when packing without bleeding; The bleeding Settings can be added when packing the bleeding on all sides. At this time, the generated single-page file will naturally remove the parts outside the page or bleeding, and the cross-page pattern text will be automatically separated.
