The Print Shop is where your job will actually be printed. With some printing processes, they can work directly from a computer disk of your work. However, if they use conventional litho presses they need a printed copy (an 'original') of your work to produce printing plates, one plate for each ink color you have used. For simple work, a copy produced on a desktop printer may be suitable. More complicated or higher quality work requires the job to pass through a service bureau.
