Information processing apparatus, method, and product performing multiplexing processing by different methods with respect to printing and non-printing areas
An information processing apparatus includes a determination unit configured to determine a printing area and a non-printing area in image data, and an execution unit configured to execute first multiplexing processing by changing a U component in a YUV color space with respect to an area determined as a printing area in the image data and to execute second multiplexing processing by changing a Y component in a CMYK color space with respect to an area determined as a non-printing area in the image data.
1. An information processing apparatus comprising:
a determination unit configured to determine a printing area and a non-printing area in image data; and
an execution unit configured to execute first multiplexing processing by changing a C component, a M component and a Y component in a CMYK color space with respect to an area determined as a printing area in the image data and to execute second multiplexing processing by changing a Y component in a CMYK color space without changing a C component and a M component with respect to an area determined as a non-printing area in the image data.
2. The information processing apparatus according to claim 1 , wherein both the first multiplexing processing and the second multiplexing processing are processing for multiplexing identical additional information.
3. The information processing apparatus according to claim 1 , wherein the information processing apparatus is a printing apparatus.
4. An information processing apparatus comprising:
a determination unit configured to determine a printing area and a non-printing area in image data; and
an execution unit configured to execute first multiplexing processing by changing one or more components in a first color space with respect to an area determined as a printing area in the image data and to execute second multiplexing processing by changing one or more components in a second color space with respect to an area determined as a non-printing area in the image data.
5. The information processing apparatus according to claim 4 , wherein the first color space is a YUV color space and the second color space is a CMYK color space.
