Abstract
Official abstract text for this publication.
A method of printing an image with a continuous inkjet printer system employing bimodal drop size generation with pigmented inkjet ink compositions comprising a polymer additive, wherein the liquid ink is an aqueous inkjet ink comprises dispersed pigment colorant particles having a mean particle size of less than 150 nanometers and at least about 0.1 wt % of polymer additive distinct from any polymer dispersant used to disperse the pigment particles, and recirculating liquid ink supplied to the nozzle if the printer system from a liquid ink source is in-line filtered with a filter selected to be effective at retaining particles having particle sizes equal to and greater than 0.6 micrometers from the liquid ink and to pass the dispersed pigment particles. The invention enables high quality drop control in a continuous inkjet printing system.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of printing an image with a continuous inkjet printer system comprising: providing a continuous inkjet printer system, the continuous inkjet printer system comprising: a jetting module including a nozzle; a liquid source in fluid communication with the nozzle, the liquid ink source including an in-line filter for filtering the liquid ink supplied to the nozzle; a drop formation mechanism; a drop deflection mechanism; and a catcher, th…
