Optimizing document redrawing

You can choose how to view a document onscreen using drawing modes. Drawing modes don’t affect object data or print quality. You can also set preferences to control screen redrawing.

The fast drawing modes, Fast Preview and Fast Keyline, optimize redrawing by reducing blend steps to 10 and greeking (dimming) text for onscreen point sizes of 50 and below.

 
To choose a drawing mode:

Select an option from the Drawing Mode pop-up menu in the Status toolbar (Windows) or at the bottom of the Document window (Macintosh):

Preview displays the document as it will print. (You can’t preview custom, PostScript, or textured strokes and fills.)

Fast Preview displays blends with reduced steps and greeked (dimmed) text.

Keyline displays only a black hairline stroke, no fill for objects, and X-boxes for EPS images and bitmap images.

Fast Keyline displays blends with reduced steps and greeked (dimmed) text.

From left to right: Preview, Fast Preview, Keyline, Fast Keyline
 

 
To switch between Preview mode and Keyline mode:

Select View > Keyline.

This command is a toggle. A checkmark beside Keyline indicates that the document is in one of the Keyline modes. When no checkmark is displayed, the document is in one of the Preview modes.

 
To switch between fast modes and other modes:

Select View > Fast Mode or press Control+Shift+K (Windows) or Command+Shift+K (Macintosh).

These commands toggle between fast modes and other modes. A checkmark beside Fast Mode indicates the document is either in Fast Preview or Fast Keyline mode.

 
To set how scrolling affects redrawing:

1	Display redraw preferences by doing one of the following:
	In Windows, press Control+U, then click the Redraw tab.
	On the Macintosh, press Command+U, then click the Redraw category.
2	Select Redraw While Scrolling to redraw the document when you click a scroll arrow or scroll bar.
	When this option is deselected, the document is redrawn when scrolling stops.
3	Click OK.

 
To enable object previews while dragging:

1	Display object preferences by doing one of the following:
	In Windows, press Control+U, then click the Object tab.
	On the Macintosh, press Command+U, then click the Object category.
2	Deselect the Alt-Drag Copies Paths option (Windows) or the Option-Drag Copies Paths option (Macintosh), if it is selected.
3	Click OK.

 
To preview an object while dragging it:

 
To set the maximum number of objects to preview while dragging:

1	Display redraw preferences by doing one of the following:
	In Windows, press Control+U, then click the Redraw tab.
	On the Macintosh, press Command+U, then click the Redraw category.
2	Enter a value in the Preview Drag text box.
	Note: Previewing a large number of objects can slow redrawing.
3	Click OK.

 
To drag an object without previewing it:

Drag the object within the Document window.

The object’s path displays the object’s movement, similar to the way in which objects appear in Keyline mode.
