Bad Trap
What it means: This is what happens when an image is imported into a picture box, but the image is sized and/or placed in a way that there is a gap between the edge of the image and the picture box, typically resulting in a white margin at the edge of the picture box.
Problems caused: The gap between the image and the picture box will be visible in the final printed product.
How to fix: Re size the image and/or picture box to eliminate the gap between the image and the picture box.
