Abstract
An ink composition for used in an inkjet printer is provided. The ink composition includes a carrier medium, a colorant, and a silicon doping agent. The silicon doping agent may include silicic acid, silicon dioxide, or silicates. This silicon-doped ink reduces and prevents the etching of the silicon based components of the printhead. Silicon-doped inks protect the printhead from damage, thus improving printhead reliability and increasing printhead service life.
