Welcome to the high-speed world of commercial printing.

• Magenta (a reddish pink)
• Yellow
• Key (Black)

These four colors are base inks that are combined in specific proportions to create any other color. Once the color is prepared, it is applied in layers. For sharp and bright printing results, these layers aligned with one another. To achieve perfect, crisp printing, every single color must be applied in the exact same spot.
