Digital printing technology is dramatically changing the packaging/prototyping market. Packaging work is among the most color critical in the industry. Matching corporate and brand colors is essential, as is the ability to accurately reproduce spot colors. The main purposes of this experimental study are to (1) examine the quality of spot color reproduction using UV wide-format inkjet printer for digital package prototyping, and (2) establish printing workflows for digital package production. In order to examine the spot color matching capability and establish a digital printing workflow for digital package prototyping, sets of test samples were prepared. Spot colors from the Pantone color guide were used to design the spot color test chart for this study. CIE L^*a^*b^* values of Pantone color swatches were used as target values. Adobe Photoshop CC 2014 was employed to generate the spot color test chart in digital form. The designed test target was printed on different grade of paperboards and corrugated board on an EFI Vutek PV 200 UV inkjet printer. Color management with ICC profiles was used to investigate the reproduction of specific spot colors. These profiles were used to compare the device gamut and to investigate reproduction of specific spot colors. The quality of spot color matching was evaluated in terms of the ΔE₂₀₀₀ in CIE L*a*b* color space.
