Image Specifications for Posters
A great image can make or break your poster design. An image that looks great on screen may not always print the way you expect it if it isn’t the right resolution.
If you want your posters to look great when printed, you basically need a high resolution image. The higher the dots per inch (dpi) of the image you upload, the less chances of having a pixelated print result.
We recommend using photos that are at least 300 dpi, or use a vector file. Images used as a background to fill your entire design needs to be at least 1024 pixels x 768 pixels.
