Rewritable printing technology does not require a ribbon to personalize cards. The card itself holds a thermosensitive material that turns visible when heated to a temperature of 356° F (180° C) and then rapidly cooled.
The application of a lower temperature, generally in the 230-320° F (110-160° C) range, will erase any color pattern. This process leverages two chemicals that interact with each other according to selected temperature thresholds.
This heating/cooling process is handled thanks to a thermal head, similar to the one used in the Evolis printers. Note that this process can be rolled back, allowing the same card to be reused and reprinted up to 500 times.
In a blank rewritable card, the thermosensitive material is applied as a plastic layer over a substrate. The most common substrates are PVC for 0.76mm (30 mil) cards and PET for 0.25mm (10 mil) cards.
PVC cards can be supplied with magnetic stripes and contactless chips to support advanced applications. PET cards often come with a magnetic layer on the reverse side of the rewritable surface.
