What is  Margin 

and How Do I Set It Up in InDesign?

What is margin in a print ready document?

Margin is not used by your Printer so doesn't need to be visible in your Print-Ready file. However, using document Margin is good practice to keep text and important content safely within the page edge and neatly aligned with other elements in your design.

What is  Trim and  Crop Marks ?

and how do I set them up in InDesign?

What is document trim?

The  Trim Line is a design guide representing the very edge of your page (the finished size) where you want your printer to trim to. 

Your image should bleed past this line to ensure no unprinted paper is visible on the edges of your design.


The trim line does not have to be visible in your Print-Ready Artwork but Crop Marks do.

What is  Bleed 

and How Do I Set It Up in InDesign?

What is document bleed?

 Bleed  provides a buffer, typically 5mm beyond the page edge. This allows for a small margin of error when the printed sheet is trimmed down to the finished size. 

Ensuring your document has bleed prevents

unprinted paper (usually white) showing around the edges of your design.


Dragging your background images to the bleed line will ensure an edgeless, flawless print for a professional finish.
