The substrate is part of the color
Ink does not appear independently of the paper beneath it. On kraft, unprinted areas and lighter colors interact with the brown base. On white board, colors begin from a lighter surface, though coating and gloss can still change the result.
Prepare artwork for the chosen substrate. A mockup that hides the board color can create a false expectation, especially around pale colors, fine type and large unprinted areas.
