What artwork works best for custom posters?

Vector files are the most optimal file types for large-scale printing. Raster images can also work if they are 300 DPI at 46 cm x 61 cm.

Raster images are made up of a bunch of tiny pixels, while vector images are made from mathematical paths and can be infinitely scaled.

• You can increase the resolution of a raster image with Upscale.
