Abstract
Official abstract text for this publication.
In an ink film thickness distribution correction method in an ink supply apparatus including an ink fountain, a plurality of ink fountain keys, an ink fountain roller, an ink ductor roller, and an ink roller group including at least one ink form roller, the throw-off operation of the ink form roller positioned at the end of the ink roller group is performed during test printing or final printing. The ink feed operation of the ink ductor roller is stopped during test printing or final printing. The ink roller group is divided into a plurality of roller subgroups during test printing or final printing. The ink in some roller subgroups out of the divided roller subgroups is scraped and removed by an ink scraping member. An ink film thickness distribution correction apparatus is also disclosed.
