Expert Answer:

As water moves up the filter paper strip having a small drop of black ink, it takes along the dyes present in ink. The dye which is more soluble in water dissolves first, rises faster and produces a coloured spot on the paper at a higher position. The less soluble dyes dissolve a little later, rise slower and form coloured spots at lower heights.
