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.
In many cases, the relevant measurement data can be gathered from control patches included in actual production runs and then saved and categorized according to print variables. This lets operators build an archive of measurements and combine existing measurements with new profiles, whenever a new combination of inks must be profiled. Accuracy is increased by adding more overprint readings. Then process-specific information is added (ink rotation, trapping, etc.), and the final press condition is simulated on a proof.
