The point Stitch , also Punzenstich , stipple engraving or Opus Mallei is a graphical gravure printing process . The visual representation does not result from lines or areas, but solely from points of different thickness and density that form a grid . This technique is rare in modern graphics .

The engraving process point stitch is by etching puncturing style to distinguish.

For the point stitch, point-like depressions are hammered into the printing plate, which usually consists of a brightly polished copper plate, which result in different brightnesses.

In the puncturing manner, these depressions are dotted into an etching base applied to this printing plate and then etched into the printing plate with acid. Different brightnesses result from how closely the points are set or how deep they are etched.

The dotting manner is a process similar to etching , which was particularly common in the 18th century. One variant is the crayon manner .
