Abstract
Provided is a doctor blade for use with a gravure printing roll, which hardly causes fogging even when it is used for the gravure printing using aqueous ink at the same printing speed as that of the gravure printing using oil based ink, can upgrade the gravure printing using the aqueous ink to a practical level, and can have an extended service life. The doctor blade includes a doctor blade body having a distal end with a knife edge portion, for filling gravure cells with ink and scraping off surplus ink with the knife edge portion being brought into contact with a gravure printing roll through a relative movement of the doctor blade to the gravure printing roll, in which at least the knife edge portion of the doctor blade body is coated with a silicon dioxide film, and the silicon dioxide film is formed by using a perhydropolysilazane solution.
