The purple line is included to represent the 'safe zone' for your text content. Text should not extend beyond the purple line. If it does, please adjust and re-upload your file(s).
Anything placed directly on or outside the purple line is at high risk of being trimmed, which is why only your background images and background colours should be outside this line.
This line does not apply to images or background colours which extend to the edge (we can print these with full bleed).
