A novel 100 dpi 256 channel aqueous compatible piezoelectric drop-on-demand inkjet printhead module has been developed for scanning system textile printing. Both the use of water as a solvent and the high chemical reactivity of typical textile inks present challenges to the design of industrial inkjet printheads. Considerations for printhead component material selection and driver electronics protection will be reviewed. The changes made to the design in order to be compatible with typical aqueous based textile inks will be discussed. Next results from jetting performance testing of the new printhead will be compared to the baseline design using model fluid. Finally the adjustable binary mode and grayscale operation of the new printhead using VersaDropTM jetting technology will be examined.
