After the fretboard is glued to the neck it’s time the dress the frets. Though I’m always careful to press the frets evenly they will always vary in height. To even them out I start by inking the tops then I stick a long piece of sandpaper to a flat surface. When I sand along the fret tops the ink is removed only on the high spots. I continue to sand until the ink is removed from all the frets. This leaves uneve widths up and down the board. The final step is to dress or round the tops and smooth any burrs that may have developed at the ends.
