Puzzling vector mask clipping path fringe issue

Hi,
I have a PSD document that is basically a group of vector masks. These layers with their associated masks are arranged in such a way that any image can be loaded into this file and it will take on the appearance of a jigsaw puzzle. You can see the results of a flower loaded here:

Or if you cannot make out the detail for the purposes of this question you can open it in your browser here:

Anyway, the way this is supposed to work is that an arbitrary image is loaded into the PSD as the ‘Puzzle’ layer. You can see the basic layer structure and the ‘Puzzle’ layer, which is temporarily a flower, here:

There is also a ‘Pieces’ group filled with the individual vector masks with clipping paths for each piece. You can see the pieces group here:

Notice how some of the pieces are red. Once the image that is to be used at the ‘Puzzle’ layer is loaded into the document the pieces layers (pieces) that are to be uses are changed to red so they can be selected manually later. Finally there is an ‘Archive’ group used to contain the source for the paths and two styles. The style source layers are used to customize the appearance of the pieces then those styles are pasted en mass onto either the pieces that are to be visible or the ones to be invisible. You can see the archive group contents here:

Now for the question. The way this is supposed to work is I go through and do a ‘Knockout Deep’ to background to all the pieces that are to be invisible. Btw, my original idea was that I would simply make invisible (click on the layer eye) the pieces to get rid of them but reality set in and I had to come up with the cumbersome ‘style’ pasting technique. Back to the question. After I do a knockout to background the image is left with a slight outline of each piece. You should be able to see it on any of the pictures in the album. I have tried and tried to get rid of that outline – for purposes of flexibility I intentionally never stroked any of the paths. Can anyone tell me where this fringe or outline comes from and how to get rid of it? And a second question, since this is my first time to use vectors, is that if anyone has any suggestions on how to better approach this project or tips to handle it they would be greatly appreciated.
Thanks,

I’ve checked your links and cannot see any red pieces or fringeing, I also dropped my resolution to increase the size of the image without success.

don’t use vector masks much, so I wouldn’t be able to offer any solutions based on experience. The only time I have see fringeing (artefacts?) is when either the layer has been over sharpened or the effects of anti aliasing. I would post this problem to the Windows photoshop forum at http://www.Adobeforums.com

Notice when you load the screen caps the white (not red) lines that appear beside the layers palette? That is the fringe I am talking about. This line seems to be bleeding beyond the edges of the clipping path. Please let me know if you are still unable to make out what I am talking about.

That sounds like a good idea. I have not heard of that forum before. I would like to resolve the issue of finding the fringe before i go much further.

Thanks for looking,
