Artwork Guide lines
Bleed Line (Blue Lines)
Marks the area where your artwork should extend beyond the cut line. Extending designs to this line ensures a clean, edge-to-edge print without any white gaps.
Cut Line (Red Lines)
Represents the final trim size of your packaging. Keep all essential artwork and text at least 0.125 inches inside this line to avoid them being cut off.
Safety Margin (Green Lines):
Defines the safe zone for placing artwork and text. As a standard practice, keep all important elements at least 0.125 inches away from the cut line unless your design requires otherwise.
Crease Line (Black Lines):
Indicates where folds will occur on your packaging, helping ensure accurate layout and alignment.
