How to design the bleeding line reasonably for book printing

In the book printing design, designing a reasonable bleeding line can better carry out the later cutting process. It can be said that the design of blood line almost determines the specific size and final forming of printed matter. How to reasonably design the bleeding line in book printing design is not only an essential research topic for excellent China printing company, but also one of the key work of printing design.

In the printing engineering, the bleeding line will have certain specification requirements in the design. Let's talk about the specific setting method. First, a bleeding line should be set inward or outward from the boundary of the printed matter. The line set outside the print size line is the outgoing blood line, and the line set inside is the internal bleeding line. The area between the two bleeding lines is the bleeding range, which specifies the specific cutting position and determines the final forming direction of the print.

Normally. 3 mm is set between the bleeding line and the print size line. However, it should be noted that the distance between the bleeding line and the print size line must be 3mm, or 5mm can be reserved, which is determined by the thickness of the paper and specific requirements. Setting aside blood lines can not only make the picture more beautiful, but also facilitated for book printing, so it is of great significance.

The above is the general design method of bleeding line, which is applicable to most printed materials. However, if there are special printing requirements, special settings should be made according to specific requirements. However, no matter what kind of printing design, excellent bleeding line design is an important guarantee for good printing.
