Make sure your frame is of a standard SEG style having a thin outside wall and a standard SEG channel. Together the outside wall and channel combined should be between 5.2-6.1mm. See the photo to understand this critical dimension. Next: Measure the outside dimensions of your frame and enter that as your graphic size. See the photo above to understand how to determine your graphic size. Result: Moss handles the rest to size the graphic to fit your frame and we guarantee we’ll make a graphic that fits perfectly!
