The importance of dispersion quality for industrial inkjet inks

One of the most difficult aspects of developing reliable inkjet inks is creating a stable dispersion of particles within the ink. This applies to inks containing pigments for colour applications but equally to inks containing other particles for functional deposition applications, which are becoming increasingly important.

Taking a closer look at inkjet developments

With the IMI Europe Inkjet Ink Development Conference taking place on 13-14 April, 2016, WTiN’s Tansy Fall caught up with IMI’s Dr Tim Phillips to discuss the conference and also take a closer look at the progress of the digital textile printing industry, with a particular focus on inks.

(Approximately) five key issues in inkjet ink development

Tim Phillips looks at the fundamental issues facing ink developers, including the trade-off between application performance and printability, carrier choice, dispersion quality, characterisation and application-specific issues.

Controlling pigment properties for optimal inkjet results

As inkjet technology progresses, the demand for characterisation of inks as regards their pigment size, the presence of single oversized grains and overall colloidal stability is increasing. Dr Thomas Benen of Microtrac introduces the main characterisation techniques used for inkjet ink dispersions.
