Scribing (also microdot engraving, needle scribing, needle scratching) is a marking technique of Permanent Direct Part Marking for precise, clean marking, fine lines and low-noise operation

Scribing (= needle scribing, = scribing) is closely related to needle embossing. The difference is that the writing when scribing is not punched into the material with an oscillating needle, but that pressure is instead applied to a special scribing needle, which moves over the area to be marked. The result is a precise, clean marking, consisting of a fine line - and that with low-noise operation.

Prerequisite for the use of a scriber is a material surface, which is as level as possible for imprinting.

Scriber heads also have two linear axes (like needle embossers), but have a more stable design than pure embosser heads. Because greater lateral forces occur with needle scribing than with needle embossing, scribing heads have a spindle drive instead of a belt drive.

Can also be used as a needle embosser:

In addition to quieter operation and the finer typeface, needle scribers can be easily transformed into needle embossers as required. Only the needle system (accessory) needs to be replaced. Significantly larger inscription fields than with needle embossers are also possible.
