Surface Truths: A Practitioner’s Guide to CMF SpecificationColor, Material, and Finish (CMF) is the user’s first physical interaction with any product, yet the specification knowledge required to execute CMF across a global supply chain is rarely documented in one place. This guide fills that gap.Written for industrial designers, product engineers, and manufacturing partners working across the US–India–China supply chain triangle, this document covers the complete CMF specification ecosystem: from CAD color tagging and technical drawing callouts, through mold surface finish standards (SPI, VDI, Mold-Tech), material compatibility, coating specification, colorant systems, durability testing, and QA inspection protocols — through to golden sample management, multi-part assembly color matching, and vendor communication across regional standards.Each section translates design intent into manufacturing-executable language, with parallel regional standard references, cost implications, and real-world failure modes drawn from production experience.Intended as an open, freely shareable reference for the global product design and manufacturing community.Keywords: CMF, color specification, material specification, finish specification, industrial design, product development, injection molding, surface finish, Pantone, CIE Lab, mold texture, coating specification, QA, manufacturing
