What Is Extended Gamut Printing?

Extended gamut printing, a cost-effective alternative to spot coloring, expands CMYK colors to include green, orange, and violet so printers can match almost all shades and vibrancies of color without sacrificing quality.

December 17, 2020     2 minute read

It’s fair to say that brands are particular. When their names adorn something the details have to be just right, from the logo to the fonts to the colors. The last of those three can be tricky. With a wide array of shades and vibrancy, it’s not always a simple thing to match the colors of a digital image in an efficient way—unless you have access to extended gamut printing. 

Achieving consistent and vibrant color historically required brand owners to specific spot colors, adding to overall packaging cost. With the new extended gamut (EG) color formulas, printers can reach more than 90% of Pantone Matching System (PMS) colors with greater accuracy than the conventional four-color process. Many brand owners narrow the allowable color shift from the spot color standard to a ΔE of <=2.8, which can be realized on 76% of EG colors.

Extended gamut printing, sometimes referred to as expanded gamut printing, features the run of CMYK (a.k.a. four-color process) plus green, orange, and violet. Although EG printing has been around for decades, what is relatively new is the Pantone EG Color Guide that now gives the industry a clear standard to follow. As a result, printing companies have found great success matching colors with the extended gamut.  

It’s not only practical for any kind of printing—on folding cartons, labels, and marketing collateral—but it’s also much more cost-effective than printing with spot or PMS colors. 

Here’s what you need to know about extended gamut printing. 

 

The Advantages of Extended Gamut Printing

Extended gamut printing presents advantages for printers and customers alike, mostly as a more efficient alternative to printing with spot colors.

When printing with spot colors, printers have to specially formulate inks to match digital files. Some brands prefer it because it gives them more color control, but it’s a time-consuming process. In addition to mixing inks, the printer has to get up to color between each run. It leads to excess inks and printed waste as well.

As the technology has improved (extended gamut printing grew in popularity in the late 20th century and can now simulate more than 1,800 spot inks), companies have been able to replicate the quality of Pantone colors at lower costs.

The benefits cover the entire printing process. Instead of physically mixing custom inks, printers digitally pre-mix them during pre-press. They can also use extended gamut printing in combination runs. You get consistent, quality coloring, in a shorter amount of time.

Printers save money on inks, labor, and reduce waste, which results in better rates and shorter lead times. You get the folding cartons, printed collateral, and labels you want at a lower cost without sacrificing quality. 

 

Making the Right Printing Choice

Although extended gamut printing can now produce near exact matches of almost all digital images, it doesn’t always apply. For one, even though there are more than 1,800 color options, there are still some colors that are unable to be matched using EG. These include some colors on the PMS color chart, pastels, and highly fluorescent pigments. 

As mentioned above, some brands prefer printing using their spot colors because of the control it gives them to keep their materials as consistent and exact as possible. (Some have tied their brand to a certain color, such as Coca-Cola Red, the company’s “second secret formula.”)Then there are decorative effects—metallic inks that hold their color over time and add luster to your folding cartons—that fall outside extended gamut printing. 

All of these considerations make it so important to work with an experienced, qualified printer. They’ll talk you through all of your printing options, highlight the effectiveness of their extended gamut printing capabilities, and give you the most cost-effective solution for your project.
