The ad which appears to the left of your front cover (known as the zero page) is placed there automatically on the free trial. This will be removed if you sign up for a RvRapid paid account, and be replaced with standard instructions.
The RvRapid Logo on the bottom right corner of the viewer will remain on a paid Rapid subscription. However, it can be removed, and replaced with your own logo for a small once only fee.
With the Realview full premiums suite you can take the branding even further but using your colours and logos, or by completely redesigning the toolbar.
Speak with your Realview sales contact to find out more about the branding options on the RvRapid and Premium platforms.
