Ink solvents are chemical compounds used to dissolve pigments and resins, managing drying time and viscosity for high-speed industrial printing. Key components include hydrocarbons, alcohols, ketones, and esters like ethyl acetate and MEK, which ensure print durability across packaging, textiles, and commercial media.
In the world of ink, you mainly have two choices: water-based ink or oil-based ink. The term ink solvent refers to the ink containing an oil-based solution. This ink is a relatively inexpensive type of ink that is compatible with inkjet printers. An attribute of solvent inks is that it is waterproof, thus making it resistant to fading and wearing. It is a common ink used to print on different uncoated banners and vinyls because the pigment bonds well with these materials. Normally, the solvent will evaporate or be flashed off with the heaters on the printer, which will leave only the pigment on the material.
Typically, ink solvent is used to print on outdoor products because of its ability to adhere to non-absorbent materials. This ink is excellent for use with long-term outdoor banners and vinyl because it is able to resist fading for five to seven years. However, venting is important for this ink because of the presence of volatile organic compounds.
Components
- The carrier fluid in this type of ink is an oil-based carrier, and it keeps the other components in liquid form.
- Pigments produce color in solvent ink. Typically, pigments are applied in powder form in order to enhance the color quality.
- Resin is the aspect of the ink that makes the color stick and protects it from damage.
Maintenance
Regular cleanings are mandatory when using ink solvent in order to keep the printer running smoothly. The oil-based solution can be very corrosive because it does not take a lot of heat for the carrier to evaporate. If not cared for properly, the print head used with solvent ink will clog. Therefore, in order to prevent the need to purchase a new print head, the user should not let a solvent printer sit around for a few days without
