ABSTRACT:
In an ink supply amount adjustment method for a printing press, one of a density value and a color value of a printing product is measured. The difference between the measurement value and a preset reference value is obtained as a measurement difference. The first error ratio allowed with respect to the preset reference value is set as a first allowable ratio. The first allowable difference is obtained from the preset reference value and the set first allowable ratio. An ink supply amount is adjusted on the basis of the obtained measurement difference and the obtained first allowable difference. An ink supply amount adjustment apparatus is also disclosed.
