Patent Number: 7,914,102

Title: Image forming apparatus and control method thereof

Abstract: In multipass printing, a mask pattern which increases the degree of dot dispersion in each pass is used for a combination of inks for increasing glossiness when printing an image. Contrary, a mask pattern which decreases the degree of dot dispersion in each pass is used for a combination of inks for decreasing glossiness. Thus, an entire image can be made uniformly glossy by suppressing gloss unevenness within the image.
