SJH card ink signature ink test: specially for signature panels and stamp areas, strong adhesion and abrasion resistance - for bank cards, ID cards and smart cards.
A full written description of the demonstration, so the content is readable without playing the video.
This video demonstrates SJH card ink (signature ink): specially for signature panels and stamp areas, with strong adhesion and abrasion resistance - for bank cards, ID cards and smart cards.
The video shows printing in the signature panel area. The panel needs an ink layer on a plastic card body that is writable - so ballpoint and signature pen ink adheres without bleeding - while the ink layer itself bonds firmly to PVC, PET and similar card bodies. Meeting both requirements at once is the technical difficulty of this ink class.
The camera shows how the ink layer accepts writing and how it resists abrasion. Bank and ID cards endure repeated swiping, friction and flexing over years of use; if the signature or stamp area is not abrasion resistant the information blurs or comes off, directly affecting card usability. Abrasion resistance is therefore a core specification.
The video helps explain compatibility requirements. Card making involves lamination, punching, personalisation and other steps, and the ink must retain adhesion and appearance throughout. Customers should therefore provide the card body material and the process sequence so we can match the formula specifically.
| Functional | Writable film (pen and ballpoint adhere without bleeding) bonded firmly to the card body |
|---|---|
| Core specs | Adhesion and abrasion resistance under long-term swiping and flexing |
| Process fit | Compatible with lamination, punching and personalisation steps |
| Typical use | Signature panels and stamp areas on bank cards, ID cards, smart cards, membership cards |
The difficulty in card ink selection is that multiple requirements pull against each other: writable, non-bleeding, firmly bonded, abrasion resistant and lamination tolerant. Any mismatch tends to surface at volume production. We strongly recommend providing the card body material (PVC/ABS/PET etc.) and the complete card-making sequence, and letting us proof and validate before volume production - trial-and-error costs far more here than in ordinary paper printing.
