Open Files
To open one or more (VPS or TIFF) files in a new window, use the Open... menu item, or click the Open icon 
in the Job Toolbar.
You can select specific files you want to display on the front or back surfaces, whether they belong to the same job or not.
...
- From the File menu, select Open... and the Open Separation Files dialog box appears.
- The dialog box has tabs for Front Surface and Back Surface.
- Select the tab for the desired surface and click Add.
- Select the files you want to add and click Open. You will be able to view the added file names added to each surface.
- Click OK to open and view the selected files.
Add Files
You can also add additional separations to an imposition by using the Add Files 
icon. This brings up the same dialog as the Open... menu.
File Formats
Prinergy VPS+ software will open preview files with file name extension .VPS produced by Prinergy workflows.
...
VPS+ can also open LEN files for viewing, and will automatically reformat as .TIF before opening.
Viewing files from Prinergy
...
When outputting files form from Prinergy, always select Advanced TIFF Tags in Prinergy Output Process Templates, in order to embed color definitions and geometry information in VPS and TIFF files. If Advanced TIFF Tags are included in the files, VPS+ will recognize spot color names and display their color equivalents.
...
There is no ISO standard for imposition tags, and so VPS+ is not able to read proprietary imposition tags from TIFFs produced by other workflow systems.
