To generate a Book Cover Template for a Soft Cover/Perfect Bound book, select the Perfect Bound option in the Cover Type section on the Template Generator window.
In the application or software you are using to create your book cover set the size of the page, layer, drawing, canvas or whatever your application uses to define the image object to match the Template Width and Template Length (height) found in the Template Dimensions section of the Template Generator window.
Depending on your the application or software import the generated template into one of the layers. If you are using a word processor program such as MS Word see the Using MS Word to Create a Book Cover topic.
Set the layer containing the template to be on top and then use the other layers to create your book cover.
Once you have finished creating your book cover, make the layer with the template not visable or delete it so that it does not show in finished book cover.
Tips:
Always insure that your background color or images extend out to the edge of the template (into the bleed area).
The centerlines can be helpful lining up your text and images on the covers and spine, you can choose not to have them generated in the template from the Settings and Options window.
Leave some space between your text and the edge of the Spine, at least a 1/16" (0.16 cm).
Leave some space between your text and the edge of the Front and Back Covers, at least a 1/4" (0.64 cm).
Insure that you do not place text in the area of the ISBN box.
