Printing certification is an attestation that a manufacturer complies with specified standards. Printing certification is a business matter because it aligns quality expectation between printing companies and their customers, and it builds trust in the global supply chain management. The primary members of the print supply chain are print buyer, the paper mill, and the printer. Printing certification is a technical matter because it enables process control, product conformance, and proof-to-print visual match in printer's routine production. Printing certification is also a standardization matter because ISO 12647-2, an existing printing standard that focuses on conformance to process control aims, and ISO/DIS 15339-1, a new printing standard that focuses on conformance to color characterization dataset, need to be harmonized to serve the standardization need of the global print supply chain. A dilemma arises when printing conformance is affected by not how the printer prints, but the choice of the paper that the print buyer wants. This research examined the relationship between process control and product conformance in a color-managed workflow. It designed printing experiments to test the print performance according to ISO/DIS 15339-1. It was found out that process control conformity does not necessarily result in dataset conformity. It validated the use of substrate corrected dataset aims and device link technology for printing conformity on OBA paper. This research also validated the use of substrate corrected dataset aims to improve the color match between prints on OBA loaded papers and proofs on non-OBA proofing substrates.
