What do red lines and red letters mean on my digital proof?

Red lines and red letters on a digital proof are reference guides, not part of your printed design. They will not appear on the finished product.

• They mark fold lines on folded pieces like brochures.
• They label panels so you can see how the layout maps to each section.
• They flag other layout information such as trim and safe areas.

Treat them as a map of your file, not as ink that will print.
