Abstract

Method and apparatus for digital printing of textiles with application of immobilization compound on the textile prior to printing. The method comprises, finding failed printing nozzles; carrying out immobilization of the textile without using at least some of the nozzles neighboring a failed printing nozzle; and printing the textile. The immobilization generally prevents the printing ink from running, so leaving out immobilization around the failed nozzle allows ink to seep into the unprinted gap. The immobilization however also stabilizes the ink, so one embodiment keeps some of the neighboring nozzles on during the immobilization.
