The experiment is based on how paper chromatography can be used to separate inks into their dye components.
If water-insoluble pens are used in the reaction, the dyes components of the ink will not dissolve in water. Because the components of the ink did not dissolve in water, when the solution is spotted on the chromatography paper, the components of the ink will not be separated out.
