After downloading and installing the VPS software below, you may open VPS Files to proof by shift clicking each file. The files are separated by each page and color so page one with the color cyan would be filename1C. Make sure you hit shift for each color you would like to look at for each page and to open them at the same time . There will be four files for each four color page and one file for black only pages. These files will be low resolution and are not meant for proofing text.
