Sorry if this is not the appropriate place for this kind of question. So I'm a newcomer/hire in a printing company, tasked with the creation of price offers for various clients (no previous experience); While I've been learning to use the software the company is using, I wanted to go deeper into the topic of how operators are actually calculating printing costs and come up with prices for various jobs; do you know of any forum posts, books, online courses, articles whatever that would help me learn more the topic?
