Bob Binder is a retired printing and color-management professional who now works as an independent consultant through RGBinder, LLC.Bob began his career in 1978 in Grand Rapids, Michigan, working as a film stripper at Acraforms while earning a degree in Printing Management from Western Michigan University. After graduation, he moved to Evansville, Indiana, where he served as Prepress Manager at Koch Label Company in a gravure label production environment. He later relocated to Carol Stream, Illinois, and spent ten years as Prepress Manager at Jefferson-Smurfit Corporation, a folding-carton facility operating gravure and offset presses.These roles provided hands-on experience in prepress, pressroom production, and cross-process color control.Bob later returned to Grand Rapids and spent 26 years in customer-facing technical and support roles, most recently as a Solution Architect at X-Rite. His work expanded into color theory, color measurement, instrument geometry, standards development, workflow integration, and deployment of color-control systems across printing environments. He has contributed technical articles to The Big Picture and Flexo Magazine.Throughout his career, Bob has worked closely with press operators, quality managers, and production teams. That exposure shaped his practical approach to color science: measurement must connect to vision; theory must connect to application; and standards must be understood before they are trusted.This book reflects that philosophy, building color understanding from fundamentals-light, spectra, human vision, measurement assumptions, and translation models-so readers can interpret numbers accurately and apply them with confidence.
