Abstract

Abstract PURPOSE:To prevent bleeding and to provide clear recording pictures close to source pictures by thinning out black pixels and color pixels at the boundary of a black picture part and a color picture part at every other dot to be recorded. CONSTITUTION:The source pictures before a thinning processing is performed are composed of 8X8 picture elements and the pictures are constituted of the black picture part 51 where recording is performed by Bk ink, the color picture part 52 where the recording is performed by other color ink and a non-recording part 53 where nothing is recorded. In the pictures, the respective picture elements in a part where the black pixels elements and the color pixels are adjacent to each other are thinned out at every other dot and the recording is performed. In such a manner, by a processing for thinning out dots in contact with the boundary at every other dot from the respective pictures at the boundary of the black pictures and the color pictures, the contact of ink drops at a boundary part can be prevented. Thus, the generation of feathering for which the ink spreads a little along with the fibers of paper is less, the bleeding for which an intercolor boundary is blurred is prevented and the high definition pictures can be obtained.
