Note:

When printing a scanned image, you may find it more difficult to match

colors. Because scanners create the original image data using CMYK,

the data format of your image will be changed twice.

Process of color printing

A printer produces color images by printing tiny patterns of ink

dots using CMYK colors as mentioned in the previous section.

Because most ink jet printers are not able to print different

gradations of the three primary colors, they must use a halftoning

method in order to represent millions of colors or the gradation

of colors. This method is shown in the image below.

Dithering and error diffusion are the most commonly used

halftoning methods.
