When carbonization occurs, a dark color envelope is made, while the frothing produces a bright mark.

In series production, it may be useful to add additives to the plastic to increase the contrast.

Other methods are the selective removal of a surface layer (varnish) to make the underlying material visible or the engraving of the workpiece.
