We have a couple @work to put datecodes, tracability numbers etc. on PCB assemblies, but they're probably more commonly used to print e.g. freshness dates directly onto cans, bottles etc. Ours are made by Markem Imaje in France, they can also do logos, 1D and 2D codes, and I _think_ there are white inks for them as well. They are also intended for integration into some machine or process as they depend on the material moving by and sensing its speed by an encoder. Ink droplets are continuously produced from a single nozzle and electrostatically deflected in 2 axes, either into a gutter inside the print head or out through the aperture and onto the medium. Using such to print onto clear adhesive label stock might be a start, but the resolution is hmmm...limited. So long, Arno
