Non-Printable Area Layer
Use the Non-printable area layer to define areas on the card that must not be printed over. For example, placing a rectangle in the Non-printable area layer over the manual Signature field prevents the printer from printing on top of the Signature field.
When a Rectangle is added to the Non-printable area layer, it displays red and white lines on the screen for design purposes. This Rectangle blocks the contents of all layers except for the Lamination and Topcoat/RTM layers.
