Retransfer and direct-to-card printing are two common methods used in ID card printers, but they differ in the way images and text are printed onto the card:
Direct-to-card printing: In this method, images and text are printed directly onto the surface of the ID card. The print head comes into contact with the card, transferring the design elements from the ribbon to the card. While direct-to-card printing is faster and more cost-effective, it may not provide the same level of print quality, durability, and edge-to-edge coverage as retransfer printing.
Retransfer printing: This method involves a two-step process. First, the images and text are printed onto a clear retransfer film. Then, the film is thermally bonded to the surface of the card. Retransfer printing allows for higher-quality, high-resolution images and text, as well as over-the-edge printing. This process also provides improved durability and compatibility with a wider range of card materials. However, retransfer printers are typically more expensive and have a slower printing speed compared to direct-to-card printers.
Choosing between retransfer and direct-to-card printing depends on factors such as print quality, durability, card material compatibility, and budget constraints.
