Precautions for the design of the die-cutting plate layout: In the design of the die-cutting plate layout, it should be noted that the outline should not have too many acute angles, otherwise it will be easy to cause difficult separation after cutting. The paper liquid packaging box is easy to be 180-1000mm and more than 1000ml, and the packaging structure of "lined bag and low box" should be adopted. When making a plate by hand, the front side of the drawing (or film) should be pasted on the bottom plate, otherwise the row of knives will be in the same direction as the printed product sample, and normal die-cutting cannot be performed; unless the bottom surface of the printed product is to be die-cut, the reverse side can be affixed to the bottom plate. When making a die-cutting plate, it is necessary to consider the needle position of the printed matter, the position and size of the bite, and whether it conforms to the use of different machines. It should be considered that in the process of calendering, laminating and other processes, the printed product will be affected by various factors such as temperature and pressure, which will lead to deformation and curling of the paper, which will bring many difficulties to die-cutting. For products with small finished product specifications, the pre-press typesetting design should consider whether the typesetting method will affect the normal production of the next process. For self-sealing boxes, pay special attention to whether a certain part of the bottom of the box protrudes from the bottom surface, causing the product packaging to not be boxed. When making a die-cut indentation plate with a box shape such as sockets, tongues, keyholes, etc., the thickness of the paper itself must be considered, otherwise the position of the guide socket will be incorrect, or the tongue will not be inserted. The lid pops up easily and automatically. For a self-sealing box, when making a die-cut indentation plate, the angle of the knife arrangement at the bottom crease should preferably be in the shape of an arc.
