Claims6
A method for processing photogravure curvilinear surfaces comprising the steps of:
- placing a first photogravure curvilinear surface onto an etching station;
- rotating said first surface and simultaneously therewith spraying an etching solution thereon for a preselected period of time;
- removing said first surface from said etching station, then placing said first surface onto an etch terminating station;
- rotating said first surface and simultaneously therewith spraying an etch terminating solution thereon for a preselected period of time;
- and,
- removing said first surface from said etch terminating station, the time of residence of said surface at each of said stations being generally the same thereby prompting the sequential continuous movement of surfaces from station to station.
