Vector, so 11 × 14 is as sharp as 5 × 7
Each print is a real vector PDF — paths, not pixels — so there’s no resolution to run out of. 5 × 7, 8 × 10, 11 × 14 and A4 are all in the folder, each in ink-on-paper and reversed for a dark frame. Print at home, or send the file straight to a print shop; they’ll know exactly what to do with it.
