Embossing is part of Framework
Framework makes doing reedwork much more effective. Embossing is important to framework.
Watch the video in full screen mode, pause and move back and forth to get a really good look at the relationship between the reeds and the slots.

Here, it helps us spot some reeds that are off-center at the base. It would have been difficult to see and correct this problem had we not tightened up the tolerance of the slots.
I tried to make this simulation as realistic as possible. There's nothing like looking at a reedplate with your own eyes.
