In today’s world, where sustainability is becoming increasingly important, industries are seeking eco-friendly alternatives to traditional methods. The textile industry, in particular, has been under scrutiny due to its environmental impact. Fortunately, advancements in technology have paved the way for more sustainable solutions, such as pigment inks in digital textile printing.

 Due to advancements in quality, performance, and availability, there is a growing need for digital pigment ink solutions for textile printing. Additionally, pigment inks are a more environmentally friendly option, which draws in more and more companies that care about the environment.

What is Pigment Ink Printing?

Pigment ink printing utilises pigment-based inks as an alternative to conventional dye-based inks. Pigment ink is composed of microscopic solid pigment particles suspended in a liquid carrier. Unlike dye ink, which diffuses, pigment particles remain on the surface of the printing medium. Pigment ink is also referred to as oily ink.

Pigment inks are renowned for their durability and light fastness. They are scratch-resistant, offer better UV resistance, and have water-resistant properties. Photographers, particularly those producing black and white prints, favour pigment inks for their ability to produce a broader range of monochrome shades.

Pigment inks are manufactured using pigment from organic synthesis. The pigment is suspended in a liquid and encapsulated in a synthetic resin. For example, pigment-based black ink is created by combining a dry, powdery substance consisting of carbon particles with a liquid.

Pigment inks are a popular choice for conventional printing. In fact, approximately 60 per cent of all conventionally printed fabrics are produced using pigment ink, according to Smithers.

High-quality pigment ink is made from materials that have reached the “final” stage of the degradation chain. Once the water evaporates after printing, these pigments will not change colour for a very long time. With proper care, they are reported to last hundreds of years.

What are the Benefits of using Pigment Inks?

Manufacturers have invested millions of dollars in developing pigment inks for digital printing. Modern digital pigments produce exceptional finishes on both blended natural and synthetic fabrics.
