One thing that's a constant source of concern for many of the great people I work with is how to prepare files for print. I'm not talking about the printer at home or the one in the office, but the professional offset and digital presses used by commercial printing operations. Sending files to a print vendor to print thousands, even millions of copies for mass publication is a much bigger deal than pushing out a few copies on a desktop printer. That's why it's important that you do everything possible to give your files the best chance to print exactly the way you expected them to. In high quantities, do-overs are expensive and not always possible, so let's look at some ways we can make it right the first time.
