Image processing apparatus and image processing method that obtain multiplexed images and output print data using multiplexed image

An image processing apparatus comprising:

• an obtaining unit configured to obtain image data obtained by reading a print image in which first information is embedded by a first method and second information that is a different type of information from the first information is embedded by a second method, the first method being a method in which a shape of a pattern is changed, and the second method being a method in which a density of a pattern is changed;
• and
• an extracting unit configured to extract the first information and the second information from the image data.
