Artboard delivers with dozens of templates for backgrounds, blank standard paper, and popular layouts. When you first open Artboard, the Template Gallery is shown by default. Templates include a variety of paper sizes and designs, some of which are sized for poster (tiled) printing or can be shrunk to fit to a single page upon printing.
When you save a drawing created from a standard or custom template, the modifications will not affect the original file. That is, the template itself remains untouched.
