The relationships between these color density measurements and any other set of reliable color density measurements is discussed. The common pitfalls are discussed in detail. These are classified into operational, control and maintenance errors.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J13692.xml)", "source": "parsed", "updated": "2026-05-22T20:40:11.684Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ { "affiliation": "Color Technology Div., Eastman Kodak Co., Rochester 4, N.
