Using templates

To avoid design inconsistency, it is possible to create templates for documents that share common design elements.  You can use these templates later for creating new documents. 
Adobe Illustrator allows you to create and use template layers in any projects

To create a template layer in Adobe Illustrator, do one of the following:
1) Click on the arrow in the upper right hand corner of the layer window and choose New Layer.  When the window appears, name the layer, click on the box next to the word template, and click OK. 
2) Double click on the name of the layer you wish to be a template in the layer menu.  When the options box appears, click on the box next to the word template and click OK. 
3) Select the name of the layer you wish to be a template layer, click on the arrow in the upper right hand corner of the layer window and choose Template.
Once a layer has been made into a template layer, it becomes locked.  You may now make new works of art based on your template layer, either by tracing objects in the template, or simply by drawing over them.  Template layers in Adobe Illustrator are not printed.
