In an ink film thickness control method for an ink supply apparatus including an ink fountain for storing an ink, a plurality of ink fountain keys whose aperture ratios are independently adjusted to supply the ink in the ink fountain, an ink fountain roller to which the ink is supplied through the ink fountain keys, and an ink ductor roller for supplying the ink supplied to the ink fountain roller to a printing plate through an ink roller group in accordance with a feed operation, the aperture ratios of all the ink fountain keys and a rotation ratio of the ink fountain roller are set at predetermined values when the ink roller group has no ink. The ink roller group is rotated. The feed operation of the ink ductor roller is performed a predetermined number of times to form a first minimum ink film thickness distribution necessary for printing in accordance with a set value such that an ink film becomes thinner from an upstream to a downstream.
