Polymers and macromolecules are related but not identical concepts. A macromolecule is a very large molecule, typically composed of thousands or more atoms, and includes classes such as proteins, nucleic acids, and synthetic polymers. Therefore, all polymers are macromolecules, but not all macromolecules are polymers. Polymers specifically refer to large molecules formed by the repetitive bonding together of many smaller units called monomers. This distinction clarifies that while polymers always have a repeating structure from monomers, macromolecules might not, embracing a broader range of large biological and synthetic molecules.
To prevent intaglio ink from smearing, ensure the paper is properly blotted to remove excess moisture before printing. Use a high-quality, dense paper tailored for intaglio techniques to absorb the ink effectively. Adjust the ink's consistency; if it's too thin, it may spread beyond the intended area, so consider adding a bit of magnesium carbonate to thicken it without affecting its richness or depth. Ensure your printing press is set to the right pressure; too much can cause the ink to spread, while too little won't transfer it adequately. After printing, allow the print to dry thoroughly in a dust-free environment before handling. Handling the prints with care and possibly using fixatives (sparingly) can also ensure the ink stays in place once the artwork is dry.
