Anaglyph Output Issues

After I finished compositing both eyes to send out for the various encodes that we wanted to test, TrioScopics and Color Code along with traditional anaglyph encode, to see which version works best with our shows, we were having a hard time being able to get it done in the timeframe we were looking for, especially with such a short amount of footage. Unfortunately we were unable to find a place to encode the anaglyph version and we were unable to get a color code version either, so I played around with doing my own Red-Cyan anaglyph encode in Digital Fusion. The process was fairly simple and straight forward, all that is needed is to filter the right eye with cyan and the left eye with red and combine them.

To do this I simply created a cyan background and multiplied it with the right eye image, created a red background and multiplied it with the left eye image and then screened the cyan left eye over the right. This gives the anaglyph image, which worked for the most part. There was a slight problem where I was getting a ghosting outline of the opposite eye. What this gave was an offset halo on either side of the 3D object.
At this point I have been unable to remove it completely, the cyan is not completely cutting out the red pass, which is causing the ghosting. It is most prominent with white objects or objects with a strong bias in the red. Maybe the other encodes will be able to reduce it.
