Jet Breakup Dynamics of Inkjet Printing Fluids by Kashyap

2021/01/11Continuous InkJet (CIJ) printing is a common 2-Dimensional printing technique that creates jets of ink that breakup into drops as they are propelled towards a substrate to create a print. Inkjet printing has been used not only to print on paper, but to manufacture a variety of devices including OLEDs, solar cells and microfluidic devices. In many cases, the 'ink' consists of a polymer Get price
