There are two kinds of inkjet printing processes that are primarily used in inkjet printers. One is the thermal inkjet process while the other is the piezoelectric inkjet process. Some of the top manufacturers favor using the thermal inkjet process while other manufacturers in the market go for the piezoelectric inkjet process.

In the thermal inkjet process, the printer produces heat so that the printer’s ink passes through the nozzle. This leads to creation of bubbles inside the Inkjet Cartridge. Once, the ink heats up, the bubbles are forced out of the nozzles using pressure. This in turn makes the bubbles burst and finally the ink comes in contact with the printer. The vacuum created by the bursting bubble results in drawing more ink out of the cartridge.

In the piezoelectric inkjet process, the piezo crystals create pressure that pushes the ink droplets out of the nozzle. The piezo crystals contract and expand when they are exposed to electric charges and this movement forces the ink out of the ink cartridge nozzle.

The printer ink in the printer is processed by a method called dithering. The dithering method involves breaking up a color pixel into a series of dots that form a spectrum of colors. Cyan, yellow and magenta are the basic colors that an inkjet printers use. To produce a dot for printing takes a lot of precision because this determines the quality of the prints. The number of dots per inch produced by the printer and the number of layers of color graduations that it can make per dot is called as the printer resolution. The higher the resolution of the printer and the higher the number of graduations the better is the print quality. This is the process how an inkjet printer works producing top-quality prints.
