PROBLEM TO BE SOLVED: To provide an ink supply apparatus for correcting a difference of mechanical characteristics even in the case of the same printing element by obtaining an ink to key transfer function without requiring a skilled technology without necessity of a test printing having nothing to do with a production. SOLUTION: The ink supply apparatus comprises a memory means (ink to key presetting unit 2, etc.), for storing an ink to key transfer function group formed by changing a parameter (a rotational speed, etc., of an ink fountain roller 5) regarding an ink density, and a controller for controlling an ink supply amount by using an ink to key transfer function selected from the function group stored in the memory means by an approximating method or newly formed by an interpolating method. |
