| 20090033956 | IMAGE PROCESSING METHOD AND APPARATUS, AND CPU-READABLE RECORDING MEDIUM - When a color image is formed on a transparent sheet with a white color material as background color material and C, M, Y, K color materials as process color materials and has colors determined by the total amount of the color materials that are applied per unit area, image formation failures such as ink drooping and ink fixation failures are prevented from occurring. Of four colors or more including white represented by a CMYKW 1-bit pixel signal, the three colors C, M, Y (gray) are replaced with the color K. After the replacement, for three or more of C, M, Y, K, no white color ink is applied since the transparent sheet is opaque without the white color ink. This control process is effective to reduce the number of applications, i.e., the total amount of inks applied, thereby preventing image formation failures such as ink drooping from occurring. | 02-05-2009 |
| 20090033961 | IMAGE PROCESSING METHOD AND APPARATUS, AND CPU-READABLE RECORDING MEDIUM - A device CMYKW 8-bit signal supplied to an image output device is controlled so that the total amount of color materials per unit area will not exceed an upper limit therefor. Until a provisional total amount of color materials reaches a value 765, a device CMYKW 8-bit signal is output with the white color material being kept at a maximum gradation level 255. When the provisional total amount is in the range between the values 765 and 1020, the amount of the white color material is reduced from the maximum gradation level to 0 to keep the total amount be the value 765. When the provisional total amount is in the range between the values 1020 and 1275, a UCR process is performed while the amount of the white color material is kept at 0. Consequently, the total amount is kept 765 of 300% or lower all the time. | 02-05-2009 |
