Our BackDrops are printed at 600 dots per inch as opposed to 300 for our BackGrounds. BackDrops are printed with 6 ink colors where BackGrounds are 4 ink colors.  The digital file size is about 4 times larger for a BackDrop which means that the print will have more detail.  A leaf on a BackDrop may look like a leaf while on a BackGround it will be a blurred leaf with dots, grainy . On some scenes this may make a noticeable difference especially for smaller scales N and Z, but if it is a hazy eastern scene or a distant mountain there may not be any leaves or other detail and if you are 3-4 ft away you wouldn't see it anyway. You will see dots or grain on BackGrounds close-up (1-30 inch), on BackDrops there will be no dots even at a few inches.  Scenes that have sharp detail, generally noticeable on the web, may look sharper as a BackDrop even if you are a few inches away. In some cases BackDrops have as much as 10 times more detail compared to a BackGround viewed from 3 inches. BackDrop 6 ink  vs. 4 ink and new technology will give better color tone,  more color density, more contrast. BackDrops may be super sharp, postcard quality over 100 ft length with detail at 3 inch viewing distance with A+ sharpness code. If you want a detailed backdrop to blend with your layout, use a BackDrop. If you want a softer look, less detail, less contrast, less color, more subdued, viewed from at least 3-4+ feet, use a BackGround. Customers that want the "not noticed" look prefer BackGrounds.
