Next Generation Inkjet Technology: Background

Despite an inkjet of sorts being described by Lord Kelvin  in 1867, and being developed as a printing technique for around 50 years, inkjet  printing still presents us with challenging problems if we wish to fully  understand and predict ink jet printer performance.  Inkjet has grown  from a specialised means of printing variable information onto documents  and products to a multi-billion dollar industry where the printer of  choice for most domestic and many office applications is an inkjet  printer of some kind.  Applications have extending into posters,  packaging and fabrics. Beyond printing, inkjet is finding application in  dispensing, rapid prototyping, PCBs, flexible displays and flexible electronics. (picture source: CDT)



The higher accuracy and higher speeds required in the new applications of inkjet make demands beyond the current state of the art. In modern inkjet printing, jets and droplets are formed at extremely high speeds with the liquids experiencing very high shear rates. The fluids contain significant amounts of polymer and/or particulates and so have particularly complex rheological properties. The combination of these two things leads to complex and inadequately-explained behaviour. (picture source: Sunjet)


In the UK, particularly around Cambridge, are a number of Companies who are pioneers in the art, science and application of inkjet. Cambridge University has joined forces with many of these companies in a venture to study the fundamental behaviour of liquids in the circumstances encountered in an inkjet system.
