Choosing Inks for Color Printing - Spot Color vs. Process Color
Process Color works a little differently. For "full color" printing, it uses 4 inks (Cyan, Magenta, Yellow, and Black) to produce a variety of other colors.
If you own an inkjet printer, or have ever used a color copier, you might already be familiar with this. With Process Color, the inks aren't mixed together to produce different colors as with Spot Colors. These colors are created with a series of half-tone dots in each of the 4 inks as needed to create the desired color. The inset to the right helps illustrate this point, and can generally be seen in any color older comic strip or comic book. Some magazines and art prints show it too, though the resolution tends to be higher, so you might need a magnifying glass of some sort.
Hopefully this clears up a few questions regarding the way Spot Colors and Process Colors are used in commercial offset printing. Future blogs will continue to explore other ink and color topics, such as Coated vs Uncoated, RGB vs CMYK, metallic inks and more.
