Description

FIELD OF THE INVENTION [0001] The invention generally relates to the field of printing. More specifically, the invention relates to a method and system for automatically detecting defects in a printing cylinder during its fabrication process. The invention further relates to a process for fabricating a printing cylinder. BACKGROUND [0002] Several printing techniques are widely used in the printing industry, among which is a printing technique known in the printing field as “Gravure press” and “rotogravure printing”. [0003] Typically, the manufacturing of a gravure printing cylinder involves coating a cylindrical metal base (e.g., steel) with an ‘image carrier’ (e.g., copper); polishing the surface of the image carrier; engraving (such as by etching) the image on the image carrier; coating the image carrier with wear-proof layer (e.g., Chrome plating) to increase the print durability of the printing cylinder; and polishing the wear-proof layer. [0004] During printing, the printing cy...
