The dotted lines serve as important guidelines for text and images in your printed magazine.
The outer dotted line is the cutline. The inner dotted line ensures your text will be clearly visible.
For full-page images: place the image outside the outer dotted line. Placing the image exactly on, or inside the outer dotted line may result in a white border.
Please note: when working with PDF files always make sure the text is inside the inner dotted line.
