ABSTRACT:
The positive correction of a gravure printing surface is conducted by depositing into the cells of the surface a heat activatable composition that is inert at the temperature of deposition but which, upon heating the surface, causes etching of the cells. When the desired correction has been achieved the etching is terminated, for instance by washing. The compositions are preferably in the form of pastes and include novel compositions comprising alkali metal bisulphate.
