Working with researchers at Zhejiang University in China, Changxi Zheng, assistant professor of computer science at Columbia Engineering, has developed a technique that
enables hydrographic printing, a widely used industrial method for transferring color inks on a thin film to the surface of manufactured 3D objects, to color these surfaces with the most precise alignment ever attained.
One approach is to develop empirical regional models that
enable aragonite saturation state to be estimated from existing
hydrographic measurements, for which greater spatial coverage and longer time series exist in addition to higher spatial and temporal resolution.
