  Définition

  Controlled area-wise etching of positives or negatives.

  Note :

  An etching resist is used to paint out sufficiently etched areas in successive stages. Further etching is then confined to unstaged areas. The staging and the etching operations are repeated until the required densities or dot sizes are obtained.
