What is Printing Ink? : an ink used in printing and consisting of a pigment or pigments of the required color mixed with oil or varnish.
What is pigment printing ink? : Pigment ink combines water, pigment, resin, and other additives to create durable and high-quality ink. Depending on the desired outcome, the ink may be heated or cooled during its creation process.
levels of uncertainty.
Printing Inks : Pigment printing solvent inks are inks that contain pigment and resin suspended in an oil-based solvent:
Solvent: The solvent dissolves the pigment and resin, and helps the ink adhere to the substrate. The solvent evaporates or is heated off, leaving the pigment behind.
Pigment: The pigment produces color in the ink. It's usually applied in powder form to improve color quality.
Resin: The resin protects the color and helps it stick to the substrate.
Solvent inks are commonly used for printing on non-porous substrates and outdoor media because they are long-lasting, chemically resistant, and waterproof. They are also compatible with inkjet printers.
Here are some things to consider about solvent inks:
Solvent type
The type of solvent used affects how quickly the ink dries. Highly volatile solvents evaporate quickly and are used for inks that need to dry quickly. Less volatile solvents are used for inks that dry by other means, like heat or oxidation.
Solvent toxicity
Some solvents, like hydrocarbons, are flammable and toxic. Other organic solvents are less flammable and toxic, but more expensive.
Solvent remnants
Some solvent remains on the material after the ink dries, which can be corrosive to plastics. To prevent this, you can use a solvent ink receptive coating that gives the solvent something to "bite into" without damaging the material. .
