What's the deal with DPI?
DPI (also known as PPI) stands for Dots/Pixels per inch and is a way of checking the total image resolution. The more dots you can fit within an inch the higher resolution the image will be. There is a lot of conjuncture on the internet about the need for DPI but here at Divebar we recommend sending your files at 300dpi set at the desired print size. e.g. 30"x40" @ 300dpi
