What happens to the ink spots as the chromatogram develops?

As the chromatogram develops, the ink spots begin to separate and spread along the chromatography medium, typically due to differences in the solubility of the ink components in the solvent used. Lighter or more soluble components travel further up the medium, while heavier or less soluble components remain closer to the origin. This separation allows for the identification of the various pigments or dyes present in the ink, as each component will form distinct spots at different positions on the chromatogram.
