What do you mean my artwork is getting cut off?
Any elements that you do not want us to cut off in the final product must be 3 - 5mm in from the outer edge of the artwork. This is called a safe inner margin. If your text or logos are in the outer 3 - 5mm of your artwork, the artwork will be reported for risk of element cut off.
Images and background colours can go to the edge of the page, but text and logos must be in the safe area.
