Q: Why use PDF format when sending files to be printed?

PDF (portable document format) has been the standard file format for many years in the printing and signage industries.

PDF was designed especially for printing and sign-making to retain all the exact colours, fonts and other features in the file - so that you get exactly what you want when the file is printed.

As with most file formats there are various options and settings that can used - so ask your printer or sign-maker to tell you the best settings to use.

With photography and other colour-critical printing colour management is also important.
