There are two main types of printing: digital and offset. Digital is cheap and fast, process is more expensive but yields higher quality results. All printing is priced based on a few parameters: set-up fee, paper, and finishing (cuting, folding, etc.). The set-up fee can be the most expensive part of a job if you order small quantities (think about why letterpress invitations cost so much). Generally, the more you order the better the buy. Any questions?
