- inkjet systems are the continuous inkjet process and the drop-on-demand process.
- solvent-based inks with high fluidity are used and sprayed continuously out of the nozzles and the jet with deflected an electrode.
- the drop-on-demand process uses higher viscosity inks, which are sprayed from a nozzle chamber only when needed.
- the drop-on-demand method can be carried out with a "bubble jet” or "piezoelectric jet".

- Typical diameters for the nozzle openings in the drop-on-demand method are in the 10-100 ⁇ scale.
- typically larger nozzle openings in the range 30 ⁇ m are used.
- the ink formulations should, on the one hand, quickly dry on the substrate and, on the other hand, should be able to pass through the nozzle orifices flow or stay in it without clogging it. They should work largely independently of the orientation of the printhead and if necessary be well removed with appropriate cleaning agents from the printhead.
- the ink compositions must therefore be formulated accordingly and are usually filtered with a filter in the range of 0.2 to Kir ⁇ to avoid the presence of larger particles which could clog the nozzles.
- Typical constituents of an inkjet ink composition are organic or inorganic constituents such as colorants (dyes, pigments), resins and binders, organic solvents, water, salts (in particular for adjusting the conductivity for the continuous inkjet process) and other additives.
- the classification of the colorants in dyes or pigments is due to the solubility in the medium used, wherein dyes are present dissolved in the solvent and pigments are undissolved.
- the resins and binders are certain polymers and solids which are appropriately selected depending on the solubility in the ink composition or its effect in the dried printing film. Among other things, they determine or improve the adhesive properties on the substrate, for example on nonporous plastic surfaces. They also change the viscosity of the ink composition and thereby determine among other things the flow properties through the nozzles and the
- resulting droplet sizes significantly determine the resistance of the resulting print film to mechanical actions (e.g., scratching the print) or chemical agents (e.g.
- Typical additives include:
- Dispersants which increase the dispersion of pigments and other particulate materials in the ink composition.
- the dispersants may be sterically and / or electrostatically active;
- Corrosion inhibitors which counteract the corrosive action of certain salts added to increase the conductivity, for example of chlorides;
- Biocides such as fungicides and bactericides, which in water-containing inks the spread of microorganisms and others
- organic solvents are typically used to make an inkjet ink composition. These are, on the one hand, the main component of low-viscosity, high-speed solvents in order to promote rapid drying of the print image and to set an advantageous viscosity in the range from 2 to 10 mPas. On the other hand, higher-viscosity, less volatile solvents are also present in a smaller proportion in order to prevent drying of the ink composition at the nozzle during printing pauses.
