How can you tell what substances are pure or a mixture during paper chromatography?

So it you spot ink from a black pen and run that in water, you get a separation of colours. This proves that it is a mixture of compounds.
If you separated/purified and isolated these compounds. Then you spotted each of them and onto their own piece of paper, they should only show one spot when you run it in water.
Basically, if you can only see one spot in after carrying out paper chromatography. That typically indicates there is only one pure compound.
