With code quality and durability becoming increasingly important, it is clear that technological development of Continuous Ink Jet [CIJ] is needed to deliver optimal drop repeatability, high resolution, and accuracy in today’s high-speed production environments. The key to solving issues around code quality can be found in the print head.

The use of smaller, more accurate codes such as 2D barcodes or variable barcodes is predicted to rise significantly in the next five years – Domino Research

Ink plays such a critical role in the process, and best CIJ performance requires control over ink pressure, temperature and viscosity. A comprehensive range of ink is also essential, to ensure best application coverage, reliability, and performance.

As CIJ systems are used in so many different areas, some of which are classified as harsh environments, a variety of inks are needed for specific industries, whether it is EuPIA GMP and Swiss List compliant inks for the Food, Beverage and Life Sciences sectors, or heavy duty inks for Industrial manufacturing.

To be fit for the future, CIJ systems must be robust enough to withstand challenging production conditions for maximum productivity with minimal downtime.

They must also be easy to operate and maintain for low cost of ownership, without compromising overall equipment efficiency.  For example, the print head should be resistant to contamination to minimise cleaning requirements, even when using pigmented inks.  The CIJ Printer should also be able to withstand wash-down conditions, while protecting against steam and the other contaminants that may come into contact with the system.

The Science of the ink drop

Reflecting the current and future requirements of the market, and the technological capabilities needed to address them, Domino has launched the Ax-Series, a new range of Continuous Ink Jet printers optimised for the most demanding industrial environments.

In developing the new series, Domino has rewritten the rules of coding and marking by revisiting the underlying science behind CIJ and introducing innovations in three key areas. Domino’s three ‘pillars’ of innovation across the Ax-Series are:


  • the new i-Pulse print head and inks. i-Pulse controls individual ink drop formation, delivering significant advances in droplet formation, placement and ink usage for reliable, high- speed and consistent code quality.
  • the i-Techx electronics and software platform, designed to optimise lifetime return on investment and eliminate coding errors by enabling smooth integration into the production line and service support environment.
  • Domino Design, a fresh approach to the total product design to maximise productivity and ease of operation, delivering printers that are robust and reliable in the harshest environments.
