1. Opening method and printing key area
The opening method in the structural design of PP Printing Box will affect the printing layout. For example, for a flip-top PP Printing Box, the lid is usually the first area that users see, so in the printing layout, this area is often designed as a key display area. The brand logo, the main features of the product, or attractive patterns may be placed. For a drawer-type PP Printing Box, the front and side will be displayed together when the drawer is pulled out, so when printing layout, important information needs to be reasonably distributed on these two surfaces to ensure that information can be effectively conveyed in different usage scenarios. For a box with a top and bottom lid, the surface of the top and bottom lid has a large flat area, which provides space for printing larger patterns or detailed product introductions, but the visual continuity after the lid is opened should also be considered to avoid the printed content being divided too abruptly.
2. Continuity of three-dimensional structure and printing surface
When the PP Printing Box has a special three-dimensional structure, such as a polyhedron or a special-shaped structure, the printing layout needs to consider the continuity between the various faces. In structural design, the angle and connection method between the faces will affect the layout of the printed pattern. If it is a PP Printing Box in the shape of a triangular prism, there is a certain angle relationship between the three sides. When printing, it is necessary to ensure the continuity of the pattern from one side to another. For example, a wraparound pattern may be designed, extending from one side to another. This printing layout needs to accurately calculate the deformation and docking of the pattern according to the angle of the structural design to ensure visual fluency. If there are complex curve transitions between the surfaces in the structural design, the printing layout should also be adjusted accordingly. Special plate printing technology may be required to ensure the perfect presentation of the pattern on different surfaces.
3. Internal structure and hidden printing content
The internal structure of the PP Printing Box will also affect the printing layout. Some PP Printing Boxes have structures such as compartments or card slots. If these internal structures will be partially seen when the box is opened or used, then the design of the printed content of these hidden parts needs to be considered when printing the layout. For example, some auxiliary instructions, usage tips or small patterns related to the product may be printed on the compartments. However, since these contents are not the main display parts, the color and pattern design should be coordinated with the external printed content, but not too complicated to avoid affecting the overall visual effect. In addition, the internal structure may impose certain restrictions on the printing operation. For example, some locations may be difficult to print. This requires considering the accessibility of the printing equipment in advance during the structural design, so as to adjust the printing layout.
4. Structural strength and printing area and position
The structural strength distribution of the PP Printing Box is also related to the printing layout. In the structural design, some parts of the box need to withstand greater pressure or tension, such as the corners and bottom of the box. If these parts are printed with too much content or covered with heavier ink, the structural strength of the box may be affected. Therefore, when printing the layout, it is necessary to avoid printing large areas and thick ink layers in key parts of the structure. On the contrary, the key printing area can be placed on a flat surface with better structural strength, such as the middle of the side of the box or the center of the lid. This can ensure the complete display of the printed content without negatively affecting the structural strength of the PP Printing Box.
