TAPPI T 653 om-07 provides a standardized procedure for measuring the specular gloss of high-gloss papers and paperboard at 20 degrees. The method covers scope, measurement principles, gloss meter requirements, specimen holders, reference standards, sampling and conditioning, calibration, measurement procedures, reporting, precision, and related methods.
This PDF is intended for paper manufacturers, converters, coating and printing professionals, quality laboratories, and researchers who need consistent gloss measurements and reporting practices. It includes guidance for machine-direction and cross-machine-direction measurements, instrument verification, specimen preparation, reference-standard care, and interpretation of measurement variability.
Application Scope: Measurement and quality control of specular gloss on high-gloss coated, cast-coated, lacquered, highly varnished, waxed, and related paper or paperboard surfaces, as well as high-gloss ink films.
