Latex ink printing

HP Latex Inks consist of up to 65% water and are designed to avoid the hazards associated with eco-solvent and UV inks.
They contain zero Hazardous Air Pollutants (HAPs),1 are non-flammable and non-combustible.2 They don’t require any special
ventilation,3 don’t release ozone, and avoid the problematic reactive monomer chemistry.4

The liquid ink vehicle is mostly made up of water, a wetting agent, and a humectant (a substance that prevents moisture from escaping the
mixture).
This vehicle is needed for printhead reliability, and a similar compound is found in all sorts of printers—from the ones in your home to industrial presses. It carries the pigment particles (pink) and latex polymer (dark blue) through the printheads and onto the substrate, where theythen form your desired image.
