Abstract:
The print permitting ratios of the masks in the first to fourth passes of a C ink are respectively 6.2%, 37.5%, 37.5%, and 18.8%. On the other hand, the print permitting ratios of the masks in the first to fourth passes of an M ink are respectively 12.5%, 37.5%, 37.5%, and 12.5%. In this way, the respective masks are set such that a larger amount of the C ink is applied in a later pass as compared with the M ink. Thereby, it is possible to reduce an amount of the M ink to be applied later with respect to the C ink functioning to “reduce a permeation speed of an ink applied later by filling,” and it is possible to prevent a permeation speed from slowing down overall. As a result, it is possible to prevent the occurrence of beading due to a time to complete permeation becoming longer.
