The Prima 4 printers reverse transfer printing technology delivers superb print quality and is the ideal choice for printing technology embedded cards, as well as high volume batch printing. Images are printed onto a thin retransfer film in a “reverse image” and heat transferred onto the card. The quality of the finished card is comparable to off-set litho printing, but with the advantage that every card can be different.This process protects the image from the handling damage and produces a brilliant edge-to-edge image with superb registration and clarity.
The process works like this: The ID card image is printed from the YMCK dye film onto a clear retransfer film in a “reverse image” and is then laminated onto the card surface. The printed image is protected from scratching and fading by the clear film layer. In comparison, dye sublimation printers transfer the dyes directly onto the card surface using thermal transfer dye diffusion technology, followed by a thin acrylic varnish. Both methods use YMCK dye films, but the reverse transfer method uses an additional polyester transfer film.
The advantages of Reverse Transfer technology are: Amazing print qualityTrue over-the-edge printing on the cardThe ability to print cards with uneven surfacesThe ability to print onto non-PVC cards like ABS, such as smart and proximity cards PET, PVH and Polycarbonate.
