What are the key points that must be paid special attention to when designing the packaging box. 1. Size, before designing each box, we must confirm its size. When determining the size of the box, you need to look at the materials commonly used in the middle and later stages of packaging and printing of the box, that is, the thickness of the paper of the box. Most of them are corrugated and non-corrugated, corrugated, generally use E tile, and the general printing paper without corrugation is very thick. Therefore, before the design, it is necessary to determine the thickness of the printing paper, and then to scale the size. It is not necessary to design a good size, because the final object cannot be loaded after the printing paper. 2. The packaging box is also a printed matter, so we need to design and typeset design in vector software. 3. If the appearance of the box is relatively unique, then you must draw the cutting lines and group all the cutting lines together, because the color printing factory makes the mold according to your cutting lines. 4. When we design the packaging, after the knife lines are drawn, we usually print out 1:1, simply fold a box, look at the lid, and see if the middle size structure in the ear is valid. 5. The packaging box is also a printed matter, so the photos and graphics used by everyone are in the CMYK color mode. 6. The packing box generally produces the following contents.
