Chromatography
To separate dye into blue ink, you would need to use a process called chromatography. This involves dissolving the ink in a solvent and allowing it to separate based on the different properties of the dye molecules. The blue dye will travel at different rates along the chromatography paper, allowing you to isolate it as a distinct color.
To separate dye from blue ink, you can use chromatography, a technique that exploits the different affinities of the dye components for a stationary and a mobile phase. By applying a small amount of the ink onto a chromatography paper or a thin-layer chromatography plate and then placing it in a solvent, the components of the ink will travel at different rates. As the solvent moves up the paper, the various dye components will separate into distinct bands or spots, allowing for their identification and collection.
Dyes and inks are separated using a method called chromatography. Basically you put a dot of ink or the dye you to separate on a piece of chromatography paper and stand it up-right. The ink spot or dye will spread across the paper and separate into different colours.

separate water from ink using a process called distillation..
evaporation
To extract water from black ink, you can conduct a simple distillation process. Heat the ink in a container, allowing the water to evaporate while the dye and other components remain behind. The steam can then be collected and condensed back into liquid form, separating the water from the dye. However, this method may not yield pure water due to potential impurities in the ink.
You can use distillation and evaporate the water out, which will leave behind whatever made the ink blue.
To obtain colored components from blue or black ink, you can use a process called chromatography. This involves dissolving the ink in a small amount of water or alcohol and then applying it to a chromatography paper. As the solvent travels up the paper, the different pigments in the ink will separate based on their solubility and affinity for the paper, revealing various colors. This method effectively isolates the individual colored components present in the ink.
One common method to separate solvent from an ink mixture is through distillation. By heating the mixture, the solvent evaporates, leaving behind the ink components. The vapor is then condensed back into liquid form, resulting in separate solvent and ink fractions.
