SOLVED! (well a solution anyway)
While I could not get rid of the intermittent horizontal lines above my FAB image script subtitle imports in Encore CS6 I was able to get even better results by using a text script.

In my case I am using Subtitle Edit to create/edit/export subtitles. Since Encore FAB Image script was top of the export list I just went right for that initially – then I ran into two things, 1) the text quality was pretty poor because the image import only works with 2+1 colors unlike the 3+1 when entering text manually within Encore, and 2) the horizontal lines appearing on ~15% of my subtitles just looked BAD and unprofessional, especially when laying over the picture.

I’ll skip the hours spent pulling hair and get to the good stuff.

What to do:
1) In Subtitle Edit > Export choose ‘Export custom text format’
2) Create a new format and use these settings:
* {number} {start} {end} {text}
* You also have to change the timecode format to hh:mm:ss.ff (for some reason this didn’t stick for me so you’ll need to update each time you export a new track)
3)In Encore when importing subtitles select text script and choose the file you saved.

BONUS:
If like me you are dealing with chinese subtitles as well as other languages you will probably run into issues where some characters are not supported and display as boxes with X’s in them. Worse still Encore doesn’t appear to let you switch fonts to find one that may support your characters. In my case it just kept sticking to Kozuka Gothic which didn’t have what I needed.

Another long story short before you hit the final import button paste in this font: DFKai-SB, which (for me) supported everything I needed.
