Color printing

Color printing is a way of printing things, like pictures, with many different colors. It uses a set of four colors (cyan, magenta, yellow, and black) that mix together to create a wide range of colors.
To make a picture in color printing, a special machine first prints black ink on the paper. It then sprinkles little dots of cyan, magenta, and yellow ink on top. The dots of ink mix together when they hit the paper, creating different colors.

The end result is a picture that is full of color and looks just like a real photograph.
