Wacom Bridge

What is Wacom Bridge?

Wacom Bridge, which is jointly developed by Splashtop and Wacom, allows you to use Wacom tablets to draw and transmit authentic strokes to a remote computer with no lag. This technology offers even more realism, instantaneous response, and finer detail compared to the our current methods using USB redirection or remote stylus, and is a big productivity enhancer and time saver for artists across multiple creative fields.
Required Gateway version v3.28.2 or higher.

Special Feature - Mercury Inkline

No matter how fast our networks or how well our remote desktop solutions perform, we simply cannot beat the speed of light.  Project Mercury includes a feature that helps fill the space between the tip of your pen and the cursor on the host machine – Mercury Inkline.  With an animated tail that synthesizes pressure sensitivity while you paint or sculpt, Mercury Inkline gives artists confidence in their stroke.  The artist knows exactly where the ink will go before it gets there – a subtle but powerful addition to the remote desktop environment.


Enable Mercury Inkline

  1. Connect the Client computer to the Host computer
  2. Click on the Actions icon in the Ribbon
  3. Select Wacom Bridge
  4. In Wacom Center on the Client computer
  5. Click on the Project Mercury tab
  6. Enable Mercury Inkline
