I think 300"dpi"/ppi is just the traditional recommended minimum?



Back in the earlier days of digital processing, I think it was more common for customers to have created low-rez files that looked good on small low-rez monitors send them to the printers and get disappointed when the same images looked horrible printed. At the same time, higher rez files were unwieldy to email/FTP and perhaps process based on the servers, connection speeds and workstation technology at the time.
