Patent ID: 8243335

Claim:
A print apparatus comprising: a conversion unit configured to perform color conversion for a bitmap image with RGB to obtain a bitmap image with CMYK; an application unit configured to apply a screen to the obtained bitmap image with CMYK; and a print unit configured to print a result of the application, the print apparatus further comprising: a color conversion unit configured to perform color conversion for a bitmap image with RGB to obtain a bitmap image with Lab; and a determination unit configured to determine whether or not each pixel in the obtained bitmap image with Lab has lower brightness than a brightness threshold and has higher saturation than a saturation threshold which is set for each brightness, wherein the application unit applies a high screen ruling to a pixel which is determined as having lower brightness than the brightness threshold and having higher saturation than the saturation threshold which is set for each brightness, the high screen ruling being a higher screen ruling than a screen ruling that is applied to a pixel which is determined as having brightness equal to the brightness threshold or more or having saturation equal to the saturation threshold, which is set for each brightness, or less.
