Jet Black (Dye) – Ideal for customers who want to increase throughput with lower resolution printing – print 150 DPI or 200 DPI with the density of 300 DPI. Ultra black works wonderfully on corrugated boxes – drying instantly and leaving a sharp, rich impression that will not fade over time. This ink also dries very quickly in the nozzle when not printing. Ideal for applications adding variable data to preprinted forms because the ink density matches offset closely.
