The production facility, time stamp, lot number and similar information can be stored, for example, in a compact data matric code (DMC) or in a dot code.
By using special types of ink which have high resistance to gasoline, Freon and high temperatures, inkjet marking systems can now be used in a much broader range of applications. Inconspicuous marking using UV-readable ink can be applied as proof of authenticity.
In an Industry 4.0 environment, workpiece marking becomes even more important. In the smart factory, it is essential that every part can be identified. A reader on a machining center detects the marking and then "knows" how to process the part. The legibility of the marking must be guaranteed under any conditions, and that places increased demands on resolution and adhesion. Even parts with small dimensions must be marked.
First we apply a white background on a part with an alphaJET series printer and then we print a data matrix code (DMC) on top of it to achieve a high contrast and guarantee traceability.
