5. Water-based inks are often highlighted as a game changer in the printing industry. In your experience, what are the main benefits and challenges associated with these inks, and how is Lubrizol addressing these challenges for high-speed applications?

Water-based inks offer several key benefits, particularly in terms of sustainability. They are seen as a greener, environmentally friendly option due to their low VOC emissions and reduced environmental impact. Additionally, they are less harmful and more suitable for food contact applications, meeting regulatory compliance standards, and they tend to be more cost-effective compared to UV-based inks.

However, these inks also come with challenges, especially when used on non-porous substrates. Water-based formulations can require longer drying times and may cause downtime due to ink drying in nozzles. Additionally, they often require primers or overprint varnishes (OPVs) to achieve the desired performance on difficult substrates.

Lubrizol addresses these challenges through our High Solids Dispersion (HSD) technology, which provides a cost-effective solution that facilitates the transition to inkjet printing. HSD technology improves ink open time by creating a more stable dispersion, making it less prone to nozzle blockages and enabling faster print speeds with reduced downtime. It also offers more formulating flexibility, making it easier to achieve the necessary stability and performance for high-speed applications.

In addition to dispersions, Lubrizol offers binders, such as Lubrijet, that are specifically designed to enhance printability on challenging substrates. With our years of experience in the packaging industry, these binders make it possible to use water-based inks on non-porous materials, overcoming one of the biggest hurdles in adopting sustainable inkjet solutions for packaging.

6. Looking ahead, what are the major trends you see shaping the future of digital print and packaging? How is Lubrizol positioning itself to take advantage of these trends?

The future of digital print and packaging is being driven by the demand for more sustainable solutions, particularly the reduction of plastic usage. There is a growing focus on developing inks that incorporate a higher percentage of renewable raw materials, and at Lubrizol, we are continuously exploring and advancing polymer technologies to meet these needs. We are also working on solutions for inks and primers that can be de-inked and recycled more easily, contributing to more efficient recycling processes and a circular economy.

Another key trend is the customization of packaging to target specific audiences, which is becoming increasingly important as brands look to differentiate themselves in the market. Digital printing enables this by allowing for smaller, more personalized print runs, making packaging more relevant and responsive to consumer needs.

Moreover, digital inkjet printing is uniquely positioned to support these evolving trends by offering greater flexibility and reducing waste compared to traditional methods. It allows for on-demand production, which minimizes overproduction and inventory waste, and reduces the environmental footprint of packaging. As the industry shifts toward smarter, more agile production processes, digital print will play an essential role in creating more efficient and sustainable supply chains.

7. The print industry is evolving rapidly with a shift toward more sustainable practices. How do you see Lubrizol’s innovations contributing to this shift, and what role does sustainability play in your product development strategy?
