Working with Documents
The Document Setup dialog lets you change most of the settings that were available when you created a document.
To open the dialog, choose File > Document Setup… from the main menu.
Dimension and Color Settings
Document Units: Defines the global measurement units. A quick way to change the units in the course of your work is to click a measurement units button at the top left corner of the canvas where the vertical and horizontal rulers touch each other.
Color Mode: Lets you select RGB, CMYK or Grayscale.
Edit Sheets: This button gives you access to the tools that help you add and delete sheets, and also change their dimensions. This button closes the Document Setup dialog and activates the Sheets tool.
The Spacing settings control the distance between the grid lines horizontally (X) and vertically (Y).
Using the Subdivision settings, you can divide each grid cell into several parts. For example, type "3" in the X edit box to split cells into three parts horizontally.
The Show on Background option defines whether the grid should be displayed in front or behind everything else on the canvas.
The Margins check box lets you show or hide a red frame that indicates the margin area along the sheet sides. This is useful to ensure that objects are placed at certain distance from the sheet edges.
Bleeds are primarily used when document pages are printed on paper that is larger than an individual page. Then you trim the output to have a proper page size. This method is used in commercial printing.
When we set non-zero bleeds, for instance 1/2 in, we actually increate the sheet size by 1/2 in at each side. The bleed area is used to print trim marks, color bars and so on. Any object or its part placed in the bleed area will be trimmed.
Normally, you shouldn't place elements of your artwork in the bleed area. An exception is the background. If it should extend to the very edge of a page, you can make the background go even further beyond the page edge to the bleed area. This ensures that you will have no gaps between the background graphics and paper edge once pages are trimmed.
