IMO Certification refers to compliance with fire safety and flame spread standards established by the International Maritime Organization (IMO), specifically for materials used in marine environments. In the context of digital printing, IMO-certified substrates are tested and approved for use in ship interiors — such as cruise ships, yachts, ferries, and offshore platforms — where strict flammability and smoke emission regulations apply.
The key IMO regulation relevant to printed substrates is the IMO Resolution MSC.307(88), FTP Code 2010, particularly Part 5, which covers surface flammability of bulkhead, ceiling, and floor finish materials. A substrate that passes this test may be labeled as "IMO Certified" or “Wheelmark Approved”, indicating it is safe for maritime installation.
Why It Matters in Digital Print:
Printed materials used in ships must meet rigorous fire safety standards. Whether producing wallcoverings, signage, or decorative panels, using an IMO-certified substrate ensures:
Regulatory compliance with international maritime laws
Flame retardancy and low smoke generation
Suitability for interior architectural applications at sea
Designers, shipbuilders, and specifiers often require IMO certification as part of project tender documentation or safety protocols.
Common IMO-Certified Substrates:
PVC-free digital wallcoverings
Polymeric or cast vinyls with FR additives
Decorative laminates for panels and walls
Fabric-backed films or textiles
Rigid composite boards (e.g. aluminum sandwich panels)
Printing Considerations:
Use inks and overlaminates that do not compromise flame retardancy
Final printed products may require re-testing if altered substantially
Some manufacturers offer full system certification (substrate + ink + laminate)
Certification Symbols:
IMO “Wheelmark”: A CE-like mark indicating approval under the EU Marine Equipment Directive (MED)
Certificate of Fire Test Report: Issued by approved labs such as DNV, Lloyd’s Register, or Bureau Veritas
Applications:
Cruise ship cabins and corridors
Ferry lounges and stairwells
Yacht interiors
Offshore platforms and drilling rigs
Marine wayfinding and safety signage
