The personalization is a graphic print out on heavy photo quality paper which has a background color and your personalization on top. This graphic is then attached to the back of your mat to show through the personalization opening. The personalization background is the 2" x 4" inch area underneath the main picture cut-out on your mat where your personalization will be placed. You are able to choose the color of this background to coordinate with your wedding or event, the frame, your home decor, or any other theme you wish. The print will be on top of the background color either in white or black, depending on the background color you choose.
