Functional Specifications
This Card Printer utilizes two different, yet closely related printing technologies to achieve
its remarkable direct-to-card print quality for dye-sublimation and resin thermal transfer.
The Card Printer will print from any IBM-PC® or compatible running Windows® 98SE, Me,
Windows 2000 or Windows XP.
The following describes how each of these technologies works:
Function Description
Dye-
Sublimation
Dye-Sublimation is the print method the DTC400/DTC300/DTC300M uses
to produce smooth, continuous-tone images that look truly photographic.
(Note: This process uses a dye-based Ribbon roll that is partitioned by a
number of consecutive color panels.)
The panels are grouped in a repeating series of these three process colors
along the entire length of the Print Ribbon: yellow, magenta and cyan or
YMC.
The Printer always prints the yellow panel first, followed by the magenta
panel and the cyan panel. (Note: As the Print Ribbon passes beneath the
Printhead, hundreds of thermal elements within the Printhead heat the
dyes on the Ribbon. When these dyes are heated, they diffuse into the
surface of the card. 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, it is possible to print up to 16.7 million different
shades of color. (Note: This blends one color smoothly into the next,
producing photo-quality images with absolutely no dot pattern.)
Resin
Thermal
Transfer
Resin Thermal Transfer is the print method the Printer uses to print sharp
black text and crisp bar codes, which can be read by both infrared and
visible-light bar code scanners.
• Used to print ultra-fast, one-color ID cards on the
DTC400/DTC300/DTC300M. (Note: Like dye-sublimation, this process
uses the same thermal Printhead to transfer color to a card from a
resin-only Print Ribbon or the resin black (K) panel of a full color Print
Ribbon.)
• Solid dots of resin-based ink are transferred and fused to the surface of
the card. (Note: This produces durable, saturated printing.)
