Full title and description

ISO 2836:2021 — Graphic technology — Prints and printing inks — Assessment of resistance of prints to various agents. This international standard specifies laboratory methods for assessing the resistance of printed materials to liquid and solid agents (including solvents, varnishes and acids) across traditional and digital printing processes.

Abstract

Defines test procedures to evaluate how prints and printing inks withstand exposure to selected liquids and solids, solvents, varnishes and acids. The methods apply to prints on all substrates and to conventional processes (offset, screen, gravure, flexo) as well as digital processes (inkjet, electrophotography). Food-contact safety aspects are excluded.

Key bibliographic and status information as published by ISO (edition 4, 2021).

Scope

Specifies standardized methods to assess the resistance of prints and printing inks to a range of agents (liquids and solids, solvents, varnishes, acids). The procedures are intended for comparative and quality-assurance testing of printed articles across substrates and printing technologies. The standard does not address regulatory food-contact safety requirements.

Key topics and requirements

• Defined test methods for exposure of prints to liquids, solids, solvents, varnishes and acids.
• Applicability to a wide range of printing technologies: offset, screen, gravure, flexo, inkjet, electrophotography.
• Guidance on sample preparation, conditioning and interpretation of test results for comparative evaluation.
• Exclusion of food-contact/consumer-protection provisions (not intended to replace specific regulatory testing for food-contact materials).
• Intended use for quality control, R&D and material/inks qualification in print production.

Summary derived from the ISO standard abstract and scope.

Typical use and users

Used by print manufacturers, ink and coating producers, packaging converters, quality-control laboratories, test houses and R&D teams to verify durability and chemical resistance of printed items. It is commonly applied during formulation development, incoming inspection of substrates/inks, print-process qualification and complaint investigation.

Related standards

This edition (2021) revises and replaces earlier editions (for example ISO 2836:2004 and prior versions). Related ISO/TC 130 graphic-technology standards address process control, colour, media and materials testing; users often apply ISO 2836 alongside other ISO/TC 130 methods for complete print evaluation.

Keywords

FAQ

Q: What is this standard?

A: An ISO international standard (ISO 2836:2021) that specifies laboratory methods to assess the resistance of prints and printing inks to various liquid and solid agents.

Q: What does it cover?

A: Test procedures for exposure of printed samples to solvents, varnishes, acids and other agents, plus guidance on sample handling and result interpretation; applicable across conventional and digital printing processes. It does not cover food-contact regulatory requirements.

Q: Who typically uses it?

A: Print shops, ink and coating manufacturers, packaging converters, QC/test laboratories and R&D groups involved in print durability and material qualification.

Q: Is it current or superseded?

A: ISO 2836:2021 is the current published edition (edition 4, 2021) and supersedes previous editions including ISO 2836:2004.

Q: Is it part of a series?

A: It is part of the body of ISO/TC 130 graphic-technology standards, which collectively cover test methods, process control, media and materials for the print industry. Users frequently reference multiple ISO/TC 130 standards together.
