What resolution should a large format artwork for print be?
For wall-sized graphics and large banners (e.g 3m x 5m), what is an acceptable PPI for print?As I understand it 300 PPI is the typical for 'small' artworks (esp. for clean text resolution). However, for small artworks, the audience usually engages at a much closer distance. Therefore in the interests of keeping a bitmap file down to a reasonable size can you get away with a much-reduced PPI for a large format/banner print?
