Solvent-based ink
Learn what a solvent-based ink is, its purpose and how Weber Marking Systems can help you implement it!
What is solvent-based ink?
Solvent-based ink is a chemically formulated ink used in industrial marking and coding systems such as inkjet printers. It consists of color pigments or dyes dissolved in a volatile organic solvent carrier, such as acetone, ethanol, or methyl ethyl ketone (MEK). Upon deposition, the solvent evaporates rapidly, leaving behind a highly durable, permanent print directly on the substrate.
Key benefits of solvent-based ink in industrial marking
Solvent-based inks offer several advantages, including:
-
Ultra-fast drying: Matches the speeds of high-throughput production lines.
-
Superior durability: Resists abrasion, moisture, scratching, and industrial chemicals.
-
Versatile substrates: Adheres perfectly to glass, metal, plastics, and ceramics.
-
High contrast: Delivers sharp, crisp edges for reliable barcode scanning.
What differentiates solvent-based inks from water-based inks?
The primary difference between solvent-based and water-based inks lies in their carrier liquid, which dictates how they dry, what materials they can print on, and their overall durability.
| Solvent-based ink |
Drying mechanism |
Dries via rapid chemical evaporation of volatile solvents |
|---|---|---|
|
Substrate compatibility |
Formulated for non-porous surfaces (plastics, metals, glass, glossy films) | |
|
Durability and resistance |
Highly resistant to water, chemicals, scratching, and outdoor weathering | |
|
Production line speed |
Ideal for ultra-high-speed manufacturing lines due to instant drying | |
| Water-based ink |
Drying mechanism |
Dries via absorption into the material or thermal forced air |
|
Substrate compatibility |
Formulated for porous surfaces (corrugated cardboard, paper, wood, fabrics) | |
|
Durability and resistance |
Vulnerable to moisture and abrasion unless coated or treated | |
|
Production line speed |
Requires longer dry times, often slowing down non-porous production lines |
Key applications for solvent-based ink
Key application areas for solvent-based inks include:
-
Packaging Industry: Printing expiration dates on flexible plastic films.
-
Pharmaceuticals: Coding batch numbers onto aluminum blister packs.
-
Automotive & Electronics: Marking part numbers on cables and extruded pipes.
-
Logistics: Printing high-contrast barcodes on coated, non-porous outer cartons.
How can Weber Marking Systems help in this domain?
