blocks light at edges and produces sharp edges

This product went up easy and folded over the edges really well

I was on the fence about using this one building my own projection screen but having the tape around the border really does make a nice edge and adds a new dimension to the picture

It is not just decorative finish, but with its light absorbing capability, it gives a neat and sharp edge to the screen and saves time when it comes to fine tuning the projected picture and fitting it on to the screen

This blacking out of the image gives it a nice crisp edge (see picture

It may not look like much in the before and after pictures but this stuff really makes for a crisp edge as it soaks up all light and adds alot of contrast
