The IDP Smart 653379 YMCFK Colour Ribbon is the ribbon you need if you want to use IDP's SmartMark watermarking technology. Without it, SmartMark simply won't activate — so if invisible security watermarks are part of your card programme, this is a non-negotiable part of your setup.

The YMCFK panel configuration delivers full-colour printing alongside a dedicated fluorescent panel, allowing custom watermarks to be printed directly onto the card surface. It's the kind of security feature that's invisible in normal light but shows clearly under UV — exactly the sort of layered protection that makes cards meaningfully harder to replicate.

Each roll yields 500 prints, making it a practical choice for organisations running regular card issuance. Manufacturer part number: 653379.
