Characterisation study of all types of printed fluids

The aim is to understand how a fluid (such as ink) behaves in the printing system to ensure that it's suitable for a specific application. This includes criteria such as fluidity, compatibility with printheads, or stability during the printing process.

The Ardeje Printing team has the laboratory equipment required to characterise a fluid printed using DOD technology:

• Goniometer – Measures the contact angle between the fluid and a surface to assess its spreadability or adhesion to the substrate.
• Dropwatcher – Analyses the formation and behaviour of ejected droplets, including their size, velocity, and trajectory.
• Viscometer – Measures the fluid’s viscosity, a critical parameter to ensure optimal flow through the printheads.

The precision of these measurement tools, combined with expert parameter control, provides a significant advantage in the success of a fluid characterisation project. Surface tension, disparity, velocity, viscosity—these are just a few of the many parameters we can evaluate, ensuring reliable and reproducible results.
