    A printing defect of gravure printing processes in which dried bits of ink collect in a web-like formation on the back of the doctor blade, on the edges of the impression roller, or in the engraved gravure cells.

    'Cobwebbing also describes a problem of screen printing in which thin strands of ink are formed between the screen fabric and the substrate, which break off the screen and leave thin, cobweb-like strands of ink on the printed substrate. Properly formulating the solvent and adjusting the printing conditions can prevent cobwebbing.
