I have never heard of emphasis ripple marks. But that's doesn't mean they don't exist.....I guess. Maybe I know them under a different name.

Current ripple marks are asymmetrical in profile with a steep up-current side and a gentle down-current side.

Wave-formed ripple marks are sinusoidal in profile.
