The "bubble-jet" name refers to the physical process used to propel ink from the printhead. Unlike piezoelectric printers that use mechanical vibration, bubble-jet printers rely on :
: When an electric pulse is applied, the ink in contact with the resistor reaches temperatures near , causing it to vaporize into a microscopic bubble. bubble-jet printer
: Dries quickly and is less sensitive to humidity. The "bubble-jet" name refers to the physical process
: Because the ink is water-based and applied as liquid droplets, it is prone to smearing if the paper is not allowed to dry. : Because the ink is water-based and applied
While bubble-jet printers can use standard paper, specialized "PB paper" was developed to optimize ink absorption and reduce bleeding. For higher-quality results, users often employ:
: Protects dye-based inks by fixing them within a special coating. Evolution and Modern Use
Since its inception, the technology has advanced significantly. Modern heads can eject droplets 1/50th the size of original models, enabling near-perfect photographic reproduction. Today, the principles of bubble-jet printing are being adapted for cutting-edge fields like and pharmaceutical manufacturing , where thermal pulses are used to deposit precise amounts of biological cells or drug formulations.
