Which kind of colour/ink cartridge does the e-mark use?

The e-mark is based on ink-jet technology. You will find a tri-colour ink cartridge inside the e-mark, which was especially adapted for COLOP e-mark in cooperation with Hewlett Packard SPS (Specialty Printing System). The ink is water-based. Any colour combinations can be made with the three inks inside the cartridge.
 

How long does a cartridge last?

The range of the cartridge depends on several factors including size and ink coverage of the imprints. Around 5000 imprints can be made with an imprint that is 14 mm x 100 mm with a coverage of around 15 %, see example below.
 
 

Are there other inks/cartridges available than the standard COLOP e-mark cartridges?

Currently, we only have tri-colour ink cartridges that offer full-colour imprints and imprints are applicable on absorbent surfaces. Further inks are in development and will extend the range of use of the e-mark.
 
 

Can I use other cartridges than the ones for the e-mark?

No, only original tri-colour cartridges can be used. Other cartridges with the same size do not work.

Can I use the e-mark on my skin as well?

Do not use the e-mark on the skin. During operation the printhead becomes very hot and can lead to burn your skin.

On which surfaces/materials can I print on with the e-mark?

Currently, the e-mark can stamp on any absorbent surfaces, such as paper, books, cardboard, serviettes or wood. Other surfaces such as glass or metal can be stamped, but need appropriate pre-treatment. Use the COLOP label sheets to mark also other materials with the e-mark.
 
 

Is the ink waterproof?

The ink is not waterproof. When applying an appropriate pre-treatment, the resistance against external impacts can be increased.
