Ink cartridge Trodat 6/4911 — blue ink, compatible with Trodat self-inking stamps

Trodat 6/4911 blue ink cartridge is a replacement unit for Trodat self-inking stamps, developed to restore clear, consistent blue impressions for everyday stamping tasks. It fits Trodat models designed for the 6/4911 cartridge format and supplies ink formulated for long-lasting legibility on paper. The cartridge design supports easy handling and clean replacement while maintaining reliable performance across a wide range of environmental conditions.

Advantages

The cartridge uses a dual-component insert and precise ink metering to provide uniform ink distribution and prevent blotting or under-inking during its service life. The grip zones on the cartridge body enable clean handling and replacement without contacting the ink reservoir. The specially formulated ink remains stable under varying temperatures and humidity and is non-toxic and resistant to drying, supporting impressions that retain legibility over time.

Suitable for

• Office stamping of documents, invoices and forms
• Administrative and postal marking tasks
• Labeling and general rubber-stamp applications that require blue impressions

Key specifications

• Color: Blue
• Type: Replacement ink cartridge for self-inking stamps
• Compatibility: Trodat self-inking stamps that accept the 6/4911 cartridge format
• Ink properties: Non-toxic, low-drying formulation designed for durable impressions

How to use

Remove the empty cartridge from the stamp according to the stamp manufacturer’s instructions and insert the replacement 6/4911 cartridge until it clicks into place. Handle the cartridge by the grip zones to avoid contact with the ink reservoir. After installation, perform a few test impressions on scrap paper to confirm even ink distribution and correct alignment. If impressions appear too light, allow a short period of normal stamping to fully saturate the pad.

Usage recommendations

Store cartridges in a cool, dry place away from direct sunlight and extreme temperatures. Use the cartridge with compatible Trodat self-inking stamp models only. For best results, keep a spare cartridge on hand to avoid downtime and test impressions after installation to ensure consistent blue prints.
