| There are two forms of Inkjet printing which apply a liquid ink solution onto the paper by propelling droplets of the colored dye or pigment based liquid solutions through a printhead. The first Inkjet technology used was the Continuous Inkjet (CIJ) process, in which a piezoelectric crystal creates an acoustic wave that breaks up the continuous jet stream of ink into droplets. The droplets then pass through an electrostatic field gaining an electric charge which allows the cartridge to deflect the newly charged droplets onto the page when necessary. The ink which is not deflected to the page is recycled back into a reservoir tank of ink to be used again. The other process is the Drop on Demand (DOD) system, in which each drop of ink is separated into chambers inside the cartridge. Each chamber has its own piezoelectric crystal which will increase the pressure inside the chamber when an electric pulse passes through them. The pressure inside will expand the drop of ink, to form a bubble. This large pressure increase will propel the burst bubble droplets onto the page through a directed nozzle. Depending on the surface area being covered with ink the cartridge will create 1-8 bubbles at a time. Inkgrabber.com offers all three varieties of Inkjet cartridges including the Original Equipment Manufacturer (OEM) or Genuine cartridges which are created by the printer manufacturer, the Remanufactured cartridges which are refilled genuine cartridges that are tested to ensure quality performance, and the Compatible cartridges which are a generic alternative to OEM ink and can be offered at a fraction of the genuine cartridge price.
