Direct-to-card and retransfer are the two choices available in card printing technology. Direct-to-card technology is the most common type of card printing, with images being printed directly onto the surface of cards. In retransfer printing, also known as HDP printers, images are printed to a clear HDP film that is then heat-sealed to the surface of cards. Both types of printing create good quality images, but there are some important differences:
Direct-to-card printers are sensitive to card imperfections. The effects of this sensitivity include: (1) Card printing that doesn't cover the entire surface of the card. Since your printhead should not come in contact with the edge of cards, a thin white border will be left around the edge of your printed cards. (2) Difficulty printing on technology cards. If you're printing too close to the raised areas of a technology card, such as a contact chip, your printhead is at risk for damage. You may also get inconsistent print quality on technology cards because of the uneven card surface.
Retransfer printers are not sensitive to card imperfections. With this technology, the printhead does not come in direct contact with the card, therefore the potential for printhead damage is limited. Images can cover the entire card surface and you can safely print on proximity cards, smart cards, pre-punched cards, key tags, etc.
The Fargo line-up includes four direct-to-card printer models: the Fargo DTC1250e, DTC1500, DTC4250e, and DTC4500e. Choose a dual-sided Fargo direct-to-card printer if you if you will be printing on both sides of a basic PVC card and don't mind having an unprinted, white edge on cards.
The Fargo line-up includes two retransfer printer models: the Fargo HDP5000 and HDP8500. Choose a dual-sided Fargo retransfer card printer if you will be printing on both sides of a technology card (smart cards, prox cards, etc.) or if you prefer "over-the-edge" prints.
