Four-Color Printing
Four color printing is the most common printing process today.
Four color printing uses translucent inks (cyan, magenta, yellow and black or CMYK). The best way to explain this process is look closely at a poster or a billboard. Notice that each image is actually composed of many random dots of each color ink overlapping each other. The overlap of these translucent inks creates the illusion of "full-color."
This is an example of four-color printing when viewed through a "loupe" or magnifying glass.
