Ink supply amount adjustment method and system for relief printing press

摘要

Provided are an ink supply amount adjustment method and system for a relief printing press which enable a reduction in a burden of the operator by enabling automatic adjustment of an ink fountain key opening degree and an ink fountain roller rotation speed on the basis of the width or the area of a line portion measured in advance, and a reduction in costs by reducing the amount of waste paper to be produced, the relief printing press including: an ink fountain (1) for storing ink; and ink fountain keys (3 (3-1 to 3-n)) and an ink fountain roller (4) for adjusting the amount of ink supplied from the ink fountain. The width of a line portion printed on paper (W) by the relief printing press is measured by a width measuring camera (44), and the ink fountain key opening degrees and the ink fountain roller rotation speed are controlled on the basis of the obtained line-portion width.
