The base of the Colormunki puck contains two strips of low friction material. I guess this is meant to make the puck glide easily across the surface of the paper. However, I've noticed that sometimes it sort of "sticks" to the paper. It's not sticking because of dry ink. Maybe van der Waals forces or something. A smooth pass across the page can sometimes end with the puck vibrating/skidding across the page.
If you know what I'm talking about, what do you do about this?
