Abstract
Disclosed herein is a doctor blade apparatus, including a printing cylinder; a pre-wipe removing a portion of ink applied to a surface of the printing cylinder, while being spaced apart from the surface of the printing cylinder; and a blade removing the ink applied to the surface of the printing cylinder, while being in contact with the surface of the printing cylinder, whereby a life span of the blade can be remarkably improved and work suspension due to replacing the blade can be minimized. Furthermore, abrasion of the printing cylinder generating friction with the blade can be minimized, such that the entire lifespan of printing equipment can be improved.
