Choosing between UV-LED and Water-based Inkjet Inks for Digital Printing

UV-LED and aqueous inks are the leading high-quality inkjet inks for the digital printing industry because they produce fast, efficient and cost-effective results. Compatible with a wide range of applications, both options can enhance print productivity. Understanding the distinct differences and benefits each ink offers can help you determine which inkjet technology is best for your business and market needs. The following information discusses what each ink type is and some of the key differences between them.

UV-LED Inkjet Inks

UV inkjet inks are liquid until the ink is exposed to UV-LED light shortly after it touches the substrate. This process cures the ink almost immediately and forms a durable film on top of the substrate. The ink is not absorbed into the substrate, but cures on top of the material. UV-LED lamps provide a deep penetrating light source that allows for better adhesion to thicker substrates. This often results in UV inks that produce vibrant, long-lasting colors on the final printed product, making them ideal for applications with a long shelf life.

Advantages

❈ Resistant to scratching, abrasion and rubbing

❈ Ability to print on flexible and more rigid substrates

❈ Can be used in outdoor and industrial environments

❈ Sharp contrast and color consistency

❈ Resistant to water, chemicals, and solvents

Disadvantages

❈ Incompatible with highly absorbent substrates

❈ Need to consider ink regulations and safety compliance standards

❈ Capital investment may be high at first

Water-based inkjet inks

Water-based inkjet inks are made from water, rather than other components such as plastic or PVC. Water-based inks use water as a medium to bring pigments (colors) into the substrate. In contrast to UV-LED, water-based inks require a longer drying time during the production process. Due to the low chemical risk associated with water-based inkjet inks, this inkjet ink technology is well suited for primary and secondary packaging applications, including food packaging production.

Advantages

❈ Wide application compatibility

❈ Environmentally friendly

❈ High possibility of meeting different safety regulations

❈ Low maintenance required when running on press

Disadvantages

❈ Incompatible with long-term outdoor applications, best suited for indoor use

❈ Application on some substrates may be difficult due to water content

❈ Longer drying process
