Safety zone (Artwork)
In artwork templates, there is a "safety zone" about 3mm inside from the outer cutting areas.
It's important not to put text or important elements inside these zones because there's a risk they might get cut off during the final printing. If text or vital parts of the design are too close to the edge, they might not show up in the finished product. So, keeping important elements away from the safety zone ensures they stay safe and visible in the final print.
