What does a DTP Preflight check?

DTP Preflight refers to the process of checking a digital document for potential issues or errors before it is printed. The preflight process usually involves checking the following:

• Is your minimum font size minimum 5pt (Paper printing) or 8pt (Large Format)? • Is your artwork in CMYK colour mode? • Is there sufficient bleed for your artwork? • Is anything in your artwork at risk of getting cut off? • Is your image resolution 300 dpi? • Are your fonts embedded or converted to curves? • Have you added the correct Die / Template? • Is your colour set up correctly for black plate changes?
