Overview
SIST ISO 15397:2020 is an international standard developed by the International Organization for Standardization (ISO) for the graphic technology industry. This standard defines the key paper properties that should be communicated between the paper manufacturing and printing industries. It covers papers and substrates intended for various commercial and industrial printing processes, including rotogravure, cold-set web offset, heat-set web offset, sheet-fed offset, flexographic printing, and proofing substrates.
By standardizing property communication, SIST ISO 15397:2020 facilitates reliable and consistent print quality, efficient collaboration across the supply chain, and clear specification of substrate requirements for both print buyers and suppliers. Establishing a common language for reporting paper properties helps minimize errors, reduce time-to-market, and enhance overall process control in graphic arts production.
Keywords: ISO 15397, graphic paper properties, printing industry, substrate communication, print quality, paper standards
Key Topics
-
Standardized Property Communication: Lists essential paper substrate properties to be specified when purchasing or supplying paper intended for graphic reproduction.
-
Applicable Paper Types: Includes papers for rotogravure, web offset (cold-set and heat-set), sheet-fed offset, flexographic printing, and proofing substrates.
-
Core Properties to Communicate:
- Brand name and paper mill
- Grammage (basis weight)
- Bulk and thickness (single sheet and pack)
- Surface roughness/smoothness (Parker Print-Surf, Bendtsen, or Bekk methods)
- Gloss level (with relevant measurement standards)
- Opacity
- Brightness and whiteness (for visual appearance)
- Colour coordinates (L*, a*, b*) under specified lighting and observer conditions
- Supported colour gamut for prepress
- Fluorescence (optical brightening agent effect)
- Storage, aging, and testing conditions (for proofing substrates)
- Bending resistance for sheet-fed offset papers
-
Measurement Standards: References to other ISO standards for methods and parameters ensure harmonization and compatibility across industries.
Applications
The practical utility of SIST ISO 15397:2020 is extensive for stakeholders in the graphic arts and print production sectors:
- Paper Manufacturers and Suppliers: Use the standard to provide transparent, standardized specifications to printing clients, ensuring that the supplied paper matches end-use requirements.
- Printing Companies: Rely on the communicated properties to set up press parameters, optimize print quality, and maintain consistency across production batches and sites.
- Print Buyers and Publishers: Specify substrate properties with confidence in procurement, reducing risks of miscommunication or unsuitable paper being used for high-value print runs.
- Prepress Technicians and Proofing Providers: Utilize paper property data to simulate accurate print conditions and achieve reliable proof-to-press matches.
SIST ISO 15397:2020 streamlines the workflow from substrate selection to final printed product, reducing variability and supporting quality control, especially in international transactions or multi-site operations.
