Predicting Spot Color Overprints
Predicting ink behavior on a substrate can be accomplished by combining spectral modeling algorithms with spectral ink measurements, as well as the substrate's colorimetric properties.
The inability to accurately proof 'spot color overprint' or 'multi-channel profiling' or 'extended-gamut printing' poses a significant challenge—along with reliably communicating this color between all parties of the supply chain, from the brand manager to the printer. An effective and accurate way to predict the behavior of spot colors that print on top of each other is difficult to achieve. For example, if a 40 percent spot color green is overprinted by an 80 percent spot color red (green on top of red), what is the resulting color on a flexo press?
