I received a .pdf file in my email requesting me to proof. What is a PDF file?
Portable document format or .PDF for short is a universal file format developed by Adobe Systems to preserve all fonts, layout, graphics, and colors of any source document. PDF allows any file to be read by the Acrobat reader regardless of the hardware or software platform on which the file was created. You can download this free Acrobat Reader from http://www.adobe.com. The PDF proof we sent to you is a purposedly reduced medium resolution image for fast internet transportation which you can view on your computer monitors.

So PDF file is the most convenient and popular ditial proof nowadays. 90% of our customers use PDF as the only proof and have no problem with our printing.
