The main difference between oil-based ink and water-based ink lies in their composition and properties.
Oil-based ink, as the name suggests, is primarily made up of oil or a combination of oils. This type of ink is known for its rich and vibrant colors, high opacity, and ability to adhere well to various surfaces, including paper, cardboard, and non-porous materials like plastic or metal. Oil-based ink takes longer to dry compared to water-based ink, which can be an advantage when dealing with longer printing runs. However, it requires additional drying time and may smudge if not given enough time to dry completely. Solvents are typically used to clean equipment and remove oil-based ink stains.
On the other hand, water-based ink is primarily composed of water as a solvent. It contains pigments or dyes that dissolve in water, along with additives for stabilization and performance enhancement. Water-based ink is eco-friendly and has a lower level of volatile organic compounds (VOCs) compared to oil-based ink. It dries quickly due to the water component, which makes it suitable for high-speed printing processes. However, water-based ink may not adhere as well to certain surfaces and may require special coatings or treatments for optimal results. It is easier to clean up water-based ink with water or mild cleaning agents.
Both types of ink have their advantages and disadvantages, and the choice between oil-based ink and water-based ink depends on the specific printing requirements, substrate, desired print quality, and environmental considerations.
WEENTEK DTF Printer (Direct-to-Film) printers typically use a type of ink called WEENTEK DTF Pigment Ink, which is a modified form of water-based ink. WEENTEK DTF Printer ink contains water as the primary solvent along with additional components such as pigments or dyes, resins, and additives. These inks are specifically formulated for use in WEENTEK DTF Printer printing processes.
WEENTEK DTF Printer ink is designed to adhere to a variety of fabric and film surfaces, making it an ideal choice for printing on textiles and other materials. It offers good color vibrancy, opacity, and durability. WEENTEK DTF Printer ink is also known for its flexibility, allowing for stretch and movement of the printed design without cracking or peeling.
Compared to traditional water-based inks used in other printing methods, WEENTEK DTF Printer ink has some modifications to enhance its bonding with the film and fabric surfaces. It typically requires heat-activated adhesion and curing to ensure proper adherence and durability.
It’s worth noting that while WEENTEK DTF Printer ink is water-based, the process of printing with WEENTEK DTF Printer technology also involves the use of transfer film, adhesive powder, and a heat press machine for the transfer and curing of the printed design onto the fabric or other surfaces.
