图像处理装置及其控制方法
摘要：
本发明提供图像处理装置及其控制方法。该图像处理装置包括：获取单元，其获取在记录介质上定影有色调色剂、然后定影透明调色剂的双路打印中使用的第一透明调色剂量；变化量获取单元，其获取所述有色调色剂被定影到所述记录介质后的图像与使用所述第一透明调色剂量的透明调色剂在所述记录介质上进行所述双路打印后的图像之间的第一明度变化量；以及设定单元，其设定在单路打印中使用的第二透明调色剂量，使得所述第一明度变化量与第二明度变化量之间的差等于或小于阈值，该第二明度变化量是所述有色调色剂被定影到所述记录介质后的图像与所述有色调色剂及所述第二透明调色剂量的透明调色剂被定影到所述记录介质后的单路打印图像之间的明度变化量。
摘要（英）：

The present invention provides an image processing apparatus and acontrol method therefor. An image processing apparatus includes an acquiring unit configured to acquire a first amount of a transparent toner for use in 2-pass printing in which a color toner is fixed on a recording medium and then the transparent toner is fixed, a change-amount acquiring unit configured to acquire a first amount of change in lightness between an image after the color toner is fixed to the recording medium and an image after the 2-pass printing is performed on the recording medium using the first amount of the transparent toner, and a setting unit configured to set a second amount of the transparent toner for use in 1-pass printing such that a difference between the first amount of change in lightness and a second amount of change in lightness is equal to or smaller than a threshold, the second amount of change in lightness being an amount of change in lightness between the image after the color toner is fixed to the recording medium and a 1-pass printing image after the color toner and the second amount of the transparent toner are fixed to the recording medium.
