We devise algorithms to remove whitishness involved in the mesh-printed matter by a drum scanner or CCD image scanner. In the case of the single color image with a black background, we choose the pixel of minimum value among the four pixels, replacing the three with it. In the same case mentioned above and the position of the color pixel region being already-known, we obtain minimum value in the region and replace all the pixels with the minimum one. In the case of the girl with a hairband, we take the difference in absolute value between the scanned pixel and the next one, and we replace the latter with the former if the absolute value is between a certain value. By these three operations, we can get satisfactory results in removing whitishness.
