Ink jet printing is simply defined as spraying liquid ink at a receiving surface. The surface can be virtually anything, such as corrugated cases or cartons, aluminum beverage or soup cans, glass bottles, plastic bottles, bags, linoleum tiles, wires and cables-the possibilities are endless. This form of printing is inexpensive, reliable and easy to use offering a consistent print quality at almost any line speed. Ink jet printing, simply put, is a marriage of software, electrical, mechanical and chemical engineering. In short, ink jet printing is the result of hardware, inks and media working together.
