Inkjet / Deskjet Printers

Inkjet printers each feature a print head containing thousands of tiny holes, and these tiny openings drop microscopic droplets of ink onto the paper. Inkjet machines use a liquid ink produced either by either a coloured dye or a liquid that contains solid pigments in suspension. As the print head moves horizontally in the machine, the paper passes through perpendicular to it. As the page passes through, the individual holes in the print head are activated (usually by heat or electrical current depending on the manufacturer) and a small drop of ink is pushed out onto the page. This process is performed at high speed with thousands of droplets forming together to recreate the digital text or image that is being transferred onto the paper. To the naked eye, the overall image looks to be solid because the dots are so tiny.
