When using InDesign, you may see the terms "bleed", "slug" and "gutter". If you are wondering what they mean, here is a breakdown:

• Gutter: The width between columns.
• Bleed and Slug: Control how materials print beyond the page boundary.
• Bleed: Allows you to over-ride the edge of the document/paper (color, photo or text). Used mostly for printing presses where the paper may shift and you don't want white space.
• Slug: Area beyond the bleed where printers marks appear (for folding/trimming). The marks are removed during trimming.
