Adding crops and bleeds is a common step in the design and printing process, especially for documents that will be professionally printed. Here's an explanation of what crops and bleeds are, and how to add them:
-
- Crop marks are lines or indicators that show where the printed piece should be trimmed or cut after it's been printed.
- They help ensure that the final product has clean edges without any unwanted white space or unfinished graphics.
-
- Bleed is the area beyond the final trim marks where the design or image extends. It's usually an extra 1/8 inch (3mm) or more beyond the trim edge.
- Bleed is important because it allows for slight variations in the printing and cutting process without leaving white edges on the final product.
- It ensures that the color or design extends all the way to the edge of the printed piece.
Here's how to add crops and bleeds:
In Design Software (e.g., Adobe InDesign, Adobe Illustrator, or similar):
-
- Start by setting up your document with the correct dimensions, resolution, and color mode (usually CMYK for print).
- Add any margins or safety zones if needed, but make sure your actual design extends to the bleed area.
- Extend Your Design to Bleed:
-
- Ensure that any background colors or images that need to extend to the edge of the page reach into the bleed area.
-
- In most design software, you can automatically generate crop marks.
- In Adobe InDesign, for example, you can go to "File" > "Document Setup" and under the "Marks and Bleed" tab, check the "Crop Marks" option.
-
- Also in the "Marks and Bleed" tab, specify the amount of bleed your document requires (typically 1/8 inch or 3mm).
- This tells the printer where to trim the final piece.
-
- When you're ready to export your file for printing, make sure to include the crop marks and bleed.
- In Adobe InDesign, you can do this by going to "File" > "Export" and selecting a PDF preset like "PDF/X-1a:2001" or "PDF/X-4."
