Halftone Editor

The Halftone Editor tool can be accessed by clicking the in the toolbox (grouped with the other object effect tools), and it is used to interactively edit the geometry of a selected halftone (or member halftone of a group).

To edit a halftone effect, use the following steps:

Select the object containing the halftone effect.
Select the Halftone Editor tool from the toolbox.
A set of halftone geometry specific knobs and indicators are shown.
Adjust the halftone geometry knobs using the mouse to change the halftone.
To change the halftone geometry type, use the Halftone panel

The halftone editor tool can also be used to select an other object for editing, but it cannot create new halftones on other objects.

The Appearance panel can be used to setup multiple halftones on the same object. This can be done by duplicating an existing halftone effect in the Appearance panel.

When an object contains multiple halftone effects, the selected halftone in Appearance panel will be shown in the Halftone panel and edited by the interactive halftone editor.
