Monitor Calibration Strategies for Effective Digital Color Communication

As our society becomes more dependent upon electronic communication to increase global connectivity, digital communication of color has been identified as a crucial aspect of modern design, marketing, and education. Effective digital color communication hinges on the ability of electronic displays to accurately render physical colors. At PPG, a global paint and coatings company, we have defined a strategy to communicate our paint colors digitally by identifying key attributes of screens to deliver an accurate rendering. In this work, we methodically examined numerous criteria (illumination type, refresh rate, resolution, and gamut) of various monitors to determine which brands and models are most well-suited for digital color rendering. We test these monitors by calculating the ΔE displayed on the monitor between vector series panels, and the measured ΔE from a handheld spectrophotometer. In addition, we compared different screen calibration devices from third-party suppliers to establish which calibration method delivers the greatest accuracy in color communication.

Bio

Dr. Rachel Harris received a Ph.D. in Chemistry from Northwestern University in 2017, where she wrote her dissertation on the effect of surface ligands on the optoelectronic properties of quantum dots. She was awarded the National Science Foundation Graduate Research Fellowship in 2014 to pursue this work. Currently, she is a Senior Researcher at PPG Industries, where she is leading projects in digital color rendering and light-matter interactions of coatings.
