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.
