Answer :
The ink should not be touching the solvent because it can cause the ink to become contaminated.
If the ink and solvent come into contact, the chemical reactions between them can cause the ink to become diluted and less effective. Additionally, if the ink is exposed to the solvent for too long, it can cause the ink to become more difficult to remove.
This is due to the solvent breaking down the molecular structure of the ink, making it harder to remove from surfaces. Inks and solvents should always be kept separate from each other in order to maintain their quality and effectiveness.
