1. What is Four Color Process Printing?

Four Color Process Printing is a method of printing that uses only four ink colors - Cyan, Magenta, Yellow, and Black. These four ink colors are known collectively as CMYK (if you'd like to know why Black is abbreviated as "K", click the link at the bottom of this article for the explanation).

The four CMYK ink colors are used by commercial printing presses to create full-color printing. By layering these four inks in various proportions, about 16,000 colors can be produced.

Four Color Process Printing is referred to as a "Process" because the four ink colors are applied to the paper one after the other. As the paper travels through the press, the colors are applied in successive layers of tiny ink dots.

It is this successive layering process that gradually builds all the colors desired for the project. The four colors of ink dots, applied at various angles and concentrations, intermingle on the paper to form the diverse shades and hues our eyes interpret as full color printing.

If you were to look at a full color image that has been commercially printed, such as a photo in a magazine or brochure, the image will appear very vivid and detailed to the naked eye. But if you were to look at the same image under powerful magnification, you will clearly see the individual dots of Cyan, Magenta, Yellow, and Black ink.

Try it for yourself and you will learn something very interesting about four color process printing. This time-tested printing method, known for creating high quality images, is actually creating illusions. Complicated illusions that trick our brain into seeing images that exhibit hundreds of variations in color and tone, when in reality there are only dots of four colors - Cyan, Magenta, Yellow, and Black.

Illusions or not, Four Color Process Printing is an amazing process that has long been the industry standard. In fact, it was developed over a century ago and is used worldwide to produce colorful and detailed print materials.

2. Can the Four Color Process produce all Colors?

Even though Four Color Process Printing can produce thousands upon thousands of colors, there are still some limitations within its gamut of colors. Some colors, particularly those very bright or saturated, can sometimes be difficult to achieve with Four Color Process Printing.

This is where Pantone colors can often save the day. Pantone is an American company headquartered in Carlstadt, New Jersey. In the early 1960s, Pantone developed a proprietary color system known as the Pantone Matching System (PMS). There are currently over 2,000 different colors within the Pantone Matching System, which helps expand the color pallet available for print projects.

Unlike 4-Color Process Printing, which builds colors on the paper by layering Cyan, Magenta, Yellow, and Black ink dots on the paper, Pantone colors are pre-mixed from established formulas before being placed into the printing press.

Also known as PMS or "Spot" colors, Pantone colors are generally applied as solid, standalone ink impressions on the paper. However, they are sometimes used in conjunction with the four CMYK process colors.

Because Pantone colors are very consistent due to their exacting formulations, they are especially popular for corporate logos, taglines, packaging and other branding purposes.
