Abstract
The invention is to cope with the minute liquid pressure change due to drying of ink or paint, clogging due to minute dirt, and other problems occurring at the tip of the doctor blade by controlling the curvature of the doctor blade itself by applying a pressure in the direction perpendicular to the surface direction of the doctor blade located in the doctor holder, thus finely adjusting the tip of the doctor blade.

A doctor blade apparatus for printing presses comprising:
- a doctor blade made of a thin flat plate material;
- a doctor blade holder that holds the doctor blade in such a way as to make the doctor blade tip abut against a plate surface;
- and
- an adjusting unit attached to the doctor blade holder and is used to adjust the doctor blade position or angle of the doctor blade,
- wherein said adjusting unit has not more than a single fine adjustment mechanism that applies a pressure to said doctor blade from a direction perpendicular to the surface direction of the doctor blade located inside said doctor holder in order to control the degree of curving of said doctor blade itself so that the contact condition between the tip and said plate surface can be finely adjusted.
