Drop-on-demand process
Drop on demand ink jet process can be distinguished by the way, again single drop of ink is produced. When thermal ink-jet this is done by heating the liquid color to evaporation, which is thrown over the pressure of the vapor bubble, a quantity of ink from the nozzle - hence the term "bubble jet". In piezo inkjet systems, the generation of the drop is effected by a change in volume in the ink chamber due to piezoelectric effects. The ink droplet is thereby ejected from the nozzle system.

Laser process
The laser marking is a method to label various objects by means of an intense laser beam or mark. The laser light energy to the material transported there and modifies the surface texture, which is formed on the surface of a logo or image. This can, depending on the material, though a range of different processes:

Laser Colour Coating
Laser Colour Coating allows the use of a standard industrial CO2 laser, for example, YAG laser, or laser in combination with a powder coating method for non-contact marking color. DSP-PRINT-TEC GmbH, Karl-Heinz Pröstler, 3. Fraunhofer Forum, 21. Nov. 2012, Stuttgart |
