Way to Make ID Cards
Although the initial investment for a film-based system was relatively low, the time, labor, and individual cost per card was high. Plus, these cards were easily counterfeited. As a result, a new method called digital printing began to arise during the late 1980s and early 1990s.
The New Way To
Make ID Cards
... and the list goes on and on. But to truly understand the benefits of digital printing, you should understand how it works. It's surprisingly simple.
How A Digital
ID Card System Works
As you can see, digital printing really is the most advanced method currently available to produce ID cards. And the results are outstanding. Just look at all the features digital ID cards have to offer:
How Digital ID Card
Direct-to-card printing is the traditional technology used by digital card printers to print images directly onto the surface of a plastic card. It does this by heating a special print ribbon beneath a thermal printhead, resulting in the transfer of color from the ribbon to a blank card.
With new High Definition Printing technology (for part one replicas of those cards that utilize it), the printer first prints images onto a special HDP film which is then fused into the surface of a blank card through heat and pressure. Because the graphics and text are printed on the underside of the HDP film, the image is "sandwiched" between the highly durable film and the card (see diagram below). This unique process results in exceptional print quality, extreme durability, and the ability to print on virtually ANY card size or type.
With either of these remarkable digital printing technologies, there are two shared print methods both use to actually do the printing. These print methods are called dye-sublimation and resin thermal transfer.
During printing, a printhead containing hundreds of thermal elements heats the dyes on the ribbon which then vaporize and diffuse into the surface of either the card (for direct-to-card printing) or the HDP film. A separate pass is made for each of the three color panels on the ribbon. By combining the colors of each panel and by varying the heat used to transfer these colors, the printer is able to produce up to 16.7 million, photo-realistic colors.
