Best way to slit brushed aluminum composite board (to eliminate ridges)

One of our big name customers is requesting 18x24 building signs out of brushed aluminum composite. Ive noticed that our slitter leaves a ridge on each side where it cuts. Any advice on how to decrease/eliminate this?
FYI- We have a Fletcher Substrate Cutter.
Also keep in mind that a new substrate cutter is not an option, and we do know that we can have the brushed aluminum composite pre-cut from our distributor, but we would like to maximize profits.

Your input and advice is greatly appreciated.

Cheers!

We use a 1/2" steel bar- slide it along the cut edge and it curls the bur under and give a nice finished edge. Gene

sand the edge afterwards, or use a straight edge and a hand router. Cut on a table saw. The foolproof method would have someone with a CNC router cut them for you.
