So I think I know how DPI/PPI works, however I don't get how are vector pictures printed... People say you don't have to set PPI when you want to print straight from vector software, but how does it work? How big the image which is 16px in vector size going to be? (Well, I know now, because I tried it, but why?) It's about 0.6cm (0.236inch) wide on paper, compared to 16 pixels on screen which means about 68 pixels per inch. (Might be the 72 ppi, it was measured by ruler) So how does the scaling work?
