Flexography is the dominant print process in regards to the reproduction of packaging products. Packaging, particular the color and graphics, is an essential tangible element for brand owners striving for brand management. Extended gamut printing is a printing technique that can produce high color saturations on packaging samples, which can have positive implications for brand management. Currently, most information on extended gamut printing is proprietary, making it very difficult for non-print industry members to obtain and utilize information relating to the benefits of extended gamut printing. The aim of this study was to provide evidence that packaging samples with extended gamut printing can positively impact brand management. Both flexible packaging and folding carton samples were analyzed in this study by taking color measurements (through the CIE L*a*b* color space) and calculating chroma to determine color saturation. Process color packaging samples were included for comparison purposes. Extended gamut folding carton and flexible packaging samples yielded chroma values 27.12 and 31.11 higher, respectively, than their process color sample counterparts. In other words, extended gamut printing yields high chroma values, which has positive implications for brand management. The results of this study can provide brand owners with insight on methods for reproducing printed packaging to benefit brand management. This study also shows the color saturation benefits of extended gamut printing, which can entice brand owners to utilize this method for either brand colors or any graphics on a packaging sample.
