Creating Grayscale Images
ePublisher allows you to transform your original color images into grayscale versions for online viewing. If you enable the Grayscale option, ePublisher removes the color saturation of the original images when those images are transformed with your online content. ePublisher displays the color versions of your images in the preview pane to generate the preview more quickly.
To create grayscale images
Open your Stationery design project.
On the View menu, click Style Designer.
On the Project menu, click a target in the Active Target menu option that is an output format that supports this option.
In Graphic Styles, select the graphic style you want to modify.
On the Options tab, set the Grayscale option to Enabled.
