- Artwork must be in 300 dpi high resolution (minimum)
- Artwork must be able to be reproduced in physical dimension of 70cm x 180cm
so how big must the digital file be at least toproduce on such dimension?
need your advice, thank you.
180cm x 70cm at 300dpi is 21260 x 8268.
just go photoshop> new canvas > enter your specs and it'll create a canvas with your requirements lor.
